PRIORITY INFORMATION 
     This application is a continuation of U.S. application Ser. No. 16/996,802, filed on Aug. 18, 2020, the contents of which are incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates generally to semiconductor memory and methods, and more particularly, to methods and apparatuses for access to data stored in quarantined memory media. 
     BACKGROUND 
     Memory devices are typically provided as internal, semiconductor, integrated circuits in computers or other electronic systems. There are many different types of memory including volatile and non-volatile memory. Volatile memory can require power to maintain its data (e.g., host data, error data, etc.) and includes random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), synchronous dynamic random access memory (SDRAM), and thyristor random access memory (TRAM), among others. Non-volatile memory can provide persistent data by retaining stored data when not powered and can include NAND flash memory, NOR flash memory, and resistance variable memory such as phase change random access memory (PCRAM), resistive random access memory (RRAM), and magnetoresistive random access memory (MRAM), such as spin torque transfer random access memory (STT RAM), among others. 
     Memory devices can be coupled to a host (e.g., a host computing device) to write (e.g., store) data, commands, and/or instructions for use by the host while the computer or electronic system is operating. For example, data, commands, and/or instructions can be transferred between the host and the memory device(s) during operation of a computing or other electronic system.

     DETAILED DESCRIPTION 
     Methods and apparatuses related to access to data stored in quarantined memory media are described. Memory systems can include multiple types of memory media (e.g., volatile and/or non-volatile) and data (e.g., information included in) stored in the memory media often are subject to risks of the data being undesirably exposed to the public. For example, requests to write data to the memory media can often be made and accepted without a user&#39;s awareness, which can lead to the undesirable exposure of the data. According to embodiments of the present disclosure, a particular portion and/or location in the memory media can provide a data protection scheme such that data stored in the particular location can be refrained from being transferred out of the computing system. 
     A computing system including memory systems can include one or more different memory media types which can be used to write data in a computing system. Such data can be transferred between a host associated with the computing system and the memory system. The data written in memory media can be important or even critical to operation of the computing system and/or the host. There are various types of memory media, and each type of memory media includes characteristics that may be unique to the memory media type. As used herein, types of memory media can include, among others, non-volatile memory and volatile memory. 
     For example, non-volatile memory can provide persistent data by retaining written data when not powered, and non-volatile memory types can include NAND flash memory, NOR flash memory, read only memory (ROM), Electrically Erasable Programmable ROM (EEPROM), Erasable Programmable ROM (EPROM), and Storage Class Memory (SCM) that can include resistance variable memory, such as phase change random access memory (PCRAM), three-dimensional cross-point memory (e.g., 3D XPoint™), resistive random access memory (RRAM), ferroelectric random access memory (FeRAM), magnetoresistive random access memory (MRAM), and programmable conductive memory, among other types of memory. Volatile memory can require power to maintain its data (e.g., host data, error data, etc.), and volatile memory types can include random-access memory (RAM), dynamic random access memory (DRAM), and static random access memory (SRAM), among others. The characteristics of different memory media types can include features that cause tradeoffs related to performance, storage density, energy requirements read/write speed, cost, etc. In some examples, some memory media types may be faster to read/write as compared to other memory media types but less cost effective than other memory media types. In other examples, memory media types may be faster as compared to other memory media types but consume a large amount of power and reduce the life of a battery, while other memory media types can be slower and consume less power. 
     Often, applications run on the host can grant permission to access data (e.g., image data) stored in the memory media. In this case, even when the host includes various data protection scheme (e.g., data encryption) that refrains data from being illegitimately retrieved (e.g., transferred) out of the host, the data protection scheme can be undesirably, but legitimately, nullified (e.g., in contrast to user&#39;s intent) and the data can be undesirably leaked and/or exposed. As an example, the host and the memory media can be (e.g., legitimately) programmed in a way that the applications run on the host are permitted to access the data stored in the memory media, in contrast to the user&#39;s intent. In this event, even though the user may not desire the data to be exposed, the data can be undesirably accessed by applications associated with a cloud system and/or social networking service (SNS), which can lead to undesired exposure of the data to, for example, the public. 
     In contrast, embodiments herein can allow a computing system to limit (e.g., limitedly allow) and/or refrain requests to access data stored in a particular location of the computing system. Accordingly, data including sensitive information and/or information that is undesired to be exposed to another party can be selectively and/or automatically stored in the particular location and protected against various attacks and/or undesired (but legitimate) requests. As used herein, the term “location” refers to a portion and/or an area corresponding to a number of memory cells that are configured to store data. 
     In the following detailed description of the present disclosure, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration how one or more embodiments of the disclosure can be practiced. These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice the embodiments of this disclosure, and it is to be understood that other embodiments can be utilized and that process, electrical, and structural changes can be made without departing from the scope of the present disclosure. 
     As used herein, designators such as “N,” etc., particularly with respect to reference numerals in the drawings, indicate that a number of the particular feature so designation can be included. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” can include both singular and plural referents, unless the context clearly dictates otherwise. In addition, “a number of,” “at least one,” and “one or more” (e.g., a number of memory devices) can refer to one or more memory devices, whereas a “plurality of” is intended to refer to more than one of such things. Furthermore, the words “can” and “may” are used throughout this application in a permissive sense (i.e., having the potential to, being able to), not in a mandatory sense (i.e., must). The term “include,” and derivations thereof, means “including, but not limited to.” The terms “coupled,” and “coupling” mean to be directly or indirectly connected physically or for access to and movement (transmission) of commands and/or data, as appropriate to the context. The terms “data” and “data values” are used interchangeably herein and can have the same meaning, as appropriate to the context. 
     The figures herein follow a numbering convention in which the first digit or digits correspond to the figure number and the remaining digits identify an element or component in the figure. Similar elements or components between different figures can be identified by the use of similar digits. For example,  102  can reference element “ 02 ” in  FIG.  1   , and a similar element can be referenced as  202  in  FIG.  2   . A group or plurality of similar elements or components can generally be referred to herein with a single element number. For example, a plurality of reference elements  230 - 1 , . . . ,  230 -N (e.g.,  230 - 1  to  230 -N) can be referred to generally as  230 . As will be appreciated, elements shown in the various embodiments herein can be added, exchanged, and/or eliminated so as to provide a number of additional embodiments of the present disclosure. In addition, the proportion and/or the relative scale of the elements provided in the figures are intended to illustrate certain embodiments of the present disclosure and should not be taken in a limiting sense. 
       FIG.  1    is a functional block diagram in the form of a computing system  100  including an apparatus including a memory system  104  in accordance with a number of embodiments of the present disclosure. As used herein, an “apparatus” can refer to, but is not limited to, any of a variety of structures or combinations of structures, such as a circuit or circuitry, a die or dice, a module or modules, a device or devices, or a system or systems, for example. The memory system  104  can include a host interface  108 , a controller  110 , (e.g., a processor, control circuitry, hardware, firmware, and/or software) and a number of memory media devices each including control circuitry. 
     The host  102  can be a host system such as a personal laptop computer, a vehicle, a desktop computer, a digital camera, a mobile telephone, an internet-of-things (IoT) enabled device, or a memory card reader, graphics processing unit (e.g., a video card), among various other types of hosts. The host  102  can include a system motherboard and/or backplane and can include a number of memory access devices such as a number of processing resources (e.g., one or more processors, microprocessors, image processor, and/or some other type of controlling circuitry). One of ordinary skill in the art will appreciate that “a processor” can intend one or more processors, such as a parallel processing system, a number of coprocessors, etc. The host  102  can be coupled to a host interface  108  of the memory system  104  by a communication channel  103 . 
     As used herein an “IoT enabled device” can refer to devices embedded with electronics, software, sensors, actuators, and/or network connectivity which enable such devices to connect to a network and/or exchange data. Examples of IoT enabled devices include mobile phones, smart phones, tablets, phablets, computing devices, implantable devices, vehicles, home appliances, smart home devices, monitoring devices, wearable devices, devices enabling intelligent shopping systems, among other cyber-physical systems. 
     The host  102  can be responsible for executing an operating system for a computing system  100  that includes the memory system  104 . Accordingly, in some embodiments, the host  102  can be responsible for controlling operation of the memory system  104 . For example, the host  102  can execute instructions (e.g., in the form of an operating system) that manage the hardware of the computing system  100  such as scheduling tasks, executing applications, controlling peripherals, etc. 
     In some embodiments, the applications running on the computing system  100  may request access to data stored in the memory system  104  such as in a plurality of memory media  112 ,  114 , and/or  116 . Such a request can be made in various manners. For example, the request can be made explicitly such that a user handling the computing system  100  (e.g., host  102 ) may be aware of the request made by the applications. In another example, the request can be made implicitly and/or may have been already accepted by the host  102  without the user being aware of the request. Accordingly, though the user has not given an explicit permission to do so, the application can still access the data stored in the plurality of memory media  112 ,  114 , and/or  116  and the accessed data may be exposed to a public undesirably, but legitimately. 
     Therefore, providing a data protection scheme against undesired but legitimately made requests is of importance. Embodiments provides such data protection scheme by writing data to a particular location of the memory system  104  and providing a higher degree of a data protection scheme to the data stored in the particular location, which can be referred to as a quarantined location. As used herein, the term “quarantined location” refers to a location within and/or among multiple memory media that is quarantined and provided a higher degree of data protection from other locations, which can be referred to as non-quarantined location. For example, data stored in the quarantined location (e.g., quarantined locations  107 - 1 ,  107 - 2 , and/or  107 - 3 ) can be entirely refrained from being transferred out of a computing system (e.g., computing system  100 ), while data stored in the non-quarantined location can be allowed to be transferred out of the computing system. As an example, the data stored in the quarantined location can be refrained from being transferred out of the computing system regardless of a type of and/or a nature of requests made for accessing the data. 
     A non-limiting example of multiple memory media having various types are described in  FIG.  1   . For example, as illustrated in  FIG.  1   , the memory system can include memory media such as memory media  112  including control circuitry  113  and an array of DRAM memory cells  105 - 1 , memory media  114  including control circuitry  115  and an array of SCM memory cells  105 - 2 , and memory media  116  including control circuitry  117  and an array of NAND memory cells  105 - 3 . While three memory media types (e.g., DRAM  105 - 1 , SCM  105 - 2 , and/or NAND  105 - 3 ) are illustrated, embodiments are not so limited, however, and there can be more or less than three memory media types. Further, the types of memory media (e.g., types of arrays of memory cells) are not limited to the three specifically illustrated (e.g., DRAM  105 - 1 , SCM  105 - 2 , and/or NAND  105 - 3 ) in  FIG.  1   , other types of volatile and/or non-volatile memory media types are contemplated. In a number of embodiments, the controller  110 , the memory media  112 ,  114 , and  116 , and/or the host interface  108  can be physically located on a single die or within a single package, (e.g., a managed memory application). Also, in a number of embodiments, a plurality of memory media (e.g., memory media  112 ,  114 , and/or  116 ), can be included on a single memory system  104 . Also, in some embodiments, more than one memory media can include a same type of array of memory cells. For example, instead of memory media  112  having an array of DRAM memory cells and memory media  114  having an array of SCM memory cells, both memory media  112  and  114  can have an array of SCM memory cells. 
     At least one of the plurality of memory media can include a quarantined location. As a non-limiting example as illustrated in  FIG.  1   , the array of each memory media can include a quarantined location. For example, the memory media  112 ,  114 , and  116  can include quarantined locations  107 - 1  (included within the DRAM array  105 - 1 ),  107 - 2  (included within the SCM array  105 - 2 ), and  107 - 3  (included within the NAND array  105 - 3 ), respectively. In a number of embodiments, access to data stored in the quarantined location can be entirely refrained and/or limited, which can refrain applications (e.g., that may have been granted permission to access the data) from accessing the data stored in the quarantined location and protect the data against the undesirable exposure to a public. 
     Although  FIG.  1    illustrates that a quarantined location is located as a portion of each memory media  112 ,  114 , and  116 , various and/or different locations of the memory media  112 ,  114 , and/or  116  can be configured as a quarantined location. For example, one of the memory media  112 ,  114 , and/or  116  can include a quarantined location, while other memory media  112 ,  114 , and/or  116  do not include. For example, unlike how it is illustrated in  FIG.  1   , in which only a portion of the memory media is configured as a quarantined location, the entire memory media can be configured as a quarantined location. 
     As illustrated in  FIG.  1   , the controller  110  can be coupled to the host interface  108  and to the memory media DRAM  112 , SCM,  114 , and NAND  116  via one or more channels and can be used to transfer data between the memory system  104  and a host  102  having a host controller  109 . The host interface  108  can be in the form of a standardized interface. For example, when the memory system  104  is used for data storage in a computing system  100 , the interface  108  can be a serial advanced technology attachment (SATA), peripheral component interconnect express (PCIe), or a universal serial bus (USB), a double data rate (DDR) interface, among other connectors and interfaces. In general, however, interface  108  can provide an interface for passing control, address, data, and other signals between the memory system  104  and a host  102  having compatible receptors for the host interface  108 . 
     The computing system  100  can include separate integrated circuits or the host  102 , the memory system  104 , the host interface  108 , the controller  110 , and/or the memory media DRAM  112 , SCM  114 , and/or NAND  116  can be on the same integrated circuit. The computing system  100  can be, for instance, a server system and/or a high-performance computing (HPC) system and/or a portion thereof. Although the example shown in  FIG.  1    illustrates a system having a Von Neumann architecture, embodiments of the present disclosure can be implemented in non-Von Neumann architectures, which may not include one or more components (e.g., CPU, ALU, etc.) often associated with a Von Neumann architecture. 
     In some embodiment, the computing system  100  (e.g., host  102 ) can be in one of a number of operation modes, which can determine whether data received at the computing system  100  is to be stored in a quarantined location or a non-quarantined location of the plurality of memory media  112 ,  114 , and/or  116 . For example, a user may put the computing system  100  into a first operation mode (e.g., public operation mode) and data generated, obtained, and/or received during the first operation mode can be transferred to and stored in the non-quarantined locations  107 - 1 ,  107 - 2 , and/or  107 - 3 . In another example, a user may put the computing system  100  into a second operation mode (e.g., private operation mode), and data generated, obtained, and/or received during the second operation mode can be transferred to and stored in the quarantined locations  107 - 1 ,  107 - 2 , and/or  107 - 3 . 
     In some embodiment, data received at the computing system  100  can include (e.g., one or more) attributes, which can be input to a setting that determines whether the data is to be stored in a quarantined location or a non-quarantined location of memory media (e.g., memory media  112 ,  114 , and/or  116 ). As used herein, the term “setting” refers to a deterministic guideline to direct data to a particular location among memory media. For example, a setting can compare the attributes to corresponding thresholds and can determine whether each of the attributes is above or below a corresponding threshold, which can further determine whether the data is to be stored in a quarantined location or a non-quarantined location. The controller  110  and/or the host controller  109  can be configured to apply one or more settings to incoming data. 
     As used herein, the term “attributes” refers to aspects of the image data, which can relate to, for example, user&#39;s desire whether the data stored in the memory system  104  can be made available to a public. Examples of the attributes can include a nature of information included within data (e.g., and/or a subject included within image data), a geological location of the computing system  100  when and/or a time at which (e.g., or a period during which) the data were generated, obtained, and/or received. These attributes can indicate a degree of privacy, which determines whether to write data to a quarantined or in a non-quarantined location. 
     In some embodiments, a threshold can be pre-established (e.g., predetermined) and/or altered based on input from a user (e.g., host  102 ). As used herein, the term “input” refers to information about attributes included in the image data. An input can be a calibration process where a user (of the host  102 ) establishes a threshold related to the attribute. For example, the input can be a user identifying whether particular data (e.g., image data) is to be stored in a quarantined location or a non-quarantined location. Based on the input, the controller  110  and/or the host controller  109  can identify a pattern shown by (e.g., underlying) multiple inputs from a user and can alter the pre-established threshold of a setting to better accommodate user&#39;s preferences. Further details associated with identifying a pattern underlying inputs from a user and applying the pattern to alter a pre-existing setting are described below. 
       FIG.  2    is a functional block diagram in the form of a computing system  201  including multiple memory media types in accordance with a number of embodiments of the present disclosure.  FIG.  2    illustrates a computing system  201  which includes a host  202 , including a host controller  209  which can be analogous to the host  102  and host controller  109  described in connection with  FIG.  1   . Computing system  201  includes a controller  210  which can be analogous to the controller  110  described in connection with  FIG.  1   . The computing system  201  can include image sensor  230 , which can be communicatively coupled to the host  202  and produce image data. 
     As illustrated in  FIG.  2   , the memory system  204  can include memory media, such as memory media  212  including control circuitry  213  and an array of DRAM memory cells  205 - 1 , memory media  214  including control circuitry  215  and array of SCM memory cells  205 - 2 , and memory media  216  including control circuitry  217  and array of NAND memory cells  205 - 3  that can be analogous to memory media  112 ,  114 , and  116 , respectively, as described in connection with  FIG.  1   . 
     At least one of the plurality of memory media can include a quarantined location. As a non-limiting example as illustrated in  FIG.  2   , the array of each memory media can include a quarantined location. For example, the memory media  212 ,  214 , and  216  can include quarantined locations  207 - 1  (included within the DRAM array  205 - 1 )  207 - 2  (included within the SCM array  205 - 2 ), and  207 - 3  (included within the NAND array  205 - 3 ), respectively. Although  FIG.  2    illustrates that a quarantined location is located as a portion of each memory media  212 ,  214 , and  216 , various and/or different locations of the memory media  212 ,  214 , and/or  216  can be configured as a quarantined location. For example, one of the memory media  212 ,  214 , and/or  216  can include a quarantined location, while other memory media  212 ,  214 , and/or  216  do not include a quarantined location. For example, unlike how it is illustrated in  FIG.  2   , in which only a portion of the memory media is configured as a quarantined location, the entire memory media can be configured as a quarantined location. 
     The host  202  can be communicatively coupled to the sensors  230  via a physical connection (e.g., via wiring, circuitry, etc.) or remotely coupled (e.g., via a wireless signal, near field communication, Bluetooth, Bluetooth Low Energy, RFID, etc.). The host  202  can be communicatively coupled to one or more memory media types.  FIG.  2    illustrates a non-limiting example of multiple memory media types in the form of a DRAM  212  including control circuitry  213 , SCM  214  including control circuitry  215 , and a NAND  216  including control circuitry  217 . The host  202  can receive the image data generated by the image sensor  230 . In some embodiments, the host  202  can be a mobile device (e.g., a smart phone) with a display that can display image data (e.g., received via the image sensor  230  (e.g., camera) to a user. 
     In a number of embodiments, access to data stored in the quarantined location can be entirely refrained and/or limited, which can refrain applications (e.g., that may have been granted permission to access the data) from accessing the data stored in the quarantined location and protect the data against the undesirable exposure to a public. As described herein, whether to write data received at the computing system  201  can be based on one or more pre-established settings (e.g., each with respective one or more pre-established thresholds), which (e.g., whose corresponding threshold) can be altered based on inputs and/or a pattern identified from the inputs received from a user of the host  202 . 
     The inputs (e.g., form a user and/or host  202 ) can indicate which attributes of the image data deem important and/or private to a user. For example, user&#39;s inputs can include user switching between a first operation mode (e.g., public operation mode) and a second operation mode (e.g., private operation mode). For example, user&#39;s inputs can include user indicating particular data stored in a quarantined location to be stored in (e.g., transferred to) a non-quarantined location, and vice versa, which classifies data that has been classified as public data to private data, or data that has been classified as private data to public data. As used herein, the term “public data” can refer to data stored in a non-quarantined location, while the term “private data” can refer to data stored in a quarantined location. 
     There may be a pattern underlying user&#39;s inputs, and the host controller  209  and/or controller  210  can be configured to identify the pattern and utilized the pattern to generate settings and/or alter existing settings, as described below. For example, a user&#39;s inputs may indicate a pattern that image data such as photographs (e.g., generated by a camera, such as image sensor  230 ) taken while the user is at a workplace and/or home are to be stored in a quarantined location. Then, the controller  210  and/or host controller  209  can generate and/or alter a setting such that the setting directs photographs that were generated, obtained, and/or received while the user is at such private places to be automatically stored in the quarantined location even without user&#39;s explicit direction to do so. For example, regardless of a place a user is located, user&#39;s inputs may indicate a pattern that photographs having a particular subject (e.g., a person and/or an animal that the user does not desire to be exposed to others) is to be stored in a quarantined location. Then, the controller  210  and/or host controller  209  can generate and/or alter a setting such that the setting directs photographs including the particular subject to be stored in the quarantined location even without user&#39;s explicit direction to do so. For example, a user&#39;s inputs may indicate a pattern that photographs generated at particular time and/or during a particular period (e.g., 9 am to 5 pm) are to be stored in the quarantined location. Then, the controller  210  and/or host controller  209  can generate and/or alter a setting such that the setting directs photographs taken at the particular time and/or during the particular period to be stored in the quarantined location. 
     In some embodiments, a pattern underlying inputs from a user and/or host  202  can indicate that existing setting can be discarded. For example, user&#39;s inputs may indicate a pattern that photographs generated during a particular period (e.g., 9 am to 5 pm) are to be stored in the non-quarantined location. Then, the controller  210  and/or host controller  209  can discard an existing setting that previously directed photographs generated during that period to be stored in the quarantined location. 
     The pattern underlying and identified from multiple inputs from a user can further alter a threshold of a setting that may have been pre-established. For example, user&#39;s inputs may indicate a pattern that photographs taken during 7 am to 3 pm to be stored in a quarantined location. In the same example, a setting with a previously threshold of 9 am to 5 pm can be altered to have a threshold of 7 am to 3 pm based on the newly-identified pattern. 
     Each time a setting is to be generated, altered, and/or discarded, the controller  210  and/or the host controller  209  can transmit a prompt to the host  202  and/or a user of the host  202  to alert the generation and/or alternation. The prompt can be accepted and/or rejected by the user. When accepted, the controller  201  and/or the host controller  209  can proceed with generating and/or altering the setting. When rejected, the controller  201  and/or the host controller  209  can discard the generation and/or alteration suggested via the prompt and operate the computing system  201  without the suggested generation and/or alteration. 
     In some embodiments, a prompt can be transmitted (e.g., by the controller  210  and/or the host controller  209 ) to a user each time a determination is to be made on whether received data (e.g., image data) is to be stored in the quarantined location and/or the non-quarantined location. For example, when a photograph is taken and corresponding image data is received at the computing system  201  (e.g., host  202 ), a prompt may be transmitted and appeared in a display of the computing system  201 , which can give a user to select where to write the image data (e.g., to the quarantined location or non-quarantined location). 
     In a non-limiting example, an apparatus (e.g., computing system  201  and/or memory system  204 ) can include a plurality of memory media (e.g., memory media  212 ,  214 , and/or  216 ) and a controller (e.g., host controller  209  and/or controller  210 ) coupled to the plurality of memory media. At least two of the plurality of memory media can be different types of memory media (e.g., DRAM, SCM, and/or NAND as described herein). The controller can be configured to receive a plurality of image data and write first mage data to a first location of the plurality of memory media and second image data to a second location of the plurality of memory media. In response to receipt a request to transfer the plurality of image data out of the apparatus, the controller can be further configured to allow the first image data to be transferred out of the apparatus (e.g., in response to the first image data being stored in the first location) and refrain the second image from being transferred out of the apparatus (e.g., in response to the second image data being stored in the second location). In some embodiments, the first location can be a non-quarantined location and the second location can be a quarantined location (e.g.,  207 - 1 ,  207 - 2 , and/or  207 - 3 ). 
     The request to access and/or transfer the plurality of image data out of the apparatus can be a request to transfer the plurality of image data to a different memory device located external to the apparatus (e.g., computing system  201  and/or memory system  204 ). For example, the different memory device can be a network attached storage (NAS) device and/or located in a data center that are often associated with SNS and/or cloud system. Accordingly, image data (e.g., second image data) stored in a quarantined location (e.g., second location) can be refrained from being uploaded to the SNS and/or cloud system. 
     In some embodiments, the second image data stored in the second location (e.g., quarantined location) can be allowed to be transferred if a corresponding request is to transfer the second image data to a different location within the apparatus. In this example, the different location can include a different location within the same memory media (e.g., where the second location is located), a different memory media, controller  210 , and/or host  202  (e.g., host controller  209 ). 
     In some embodiments, the first location and the second location can be located and included in a same memory media (e.g., first memory media) of the plurality of memory media. In some embodiments, the first location can be located and included in a first memory media, while the second location can be located and included in a second memory media of the plurality of memory media. 
     In another non-limiting example, an apparatus (e.g., computing system  201  and/or memory system  204 ) can include a plurality of memory media (e.g., memory media  212 ,  214 , and/or  216 ). In this example, at least two of the plurality of memory media can be different types (e.g., DRAM, SCM, and/or NAND as described herein) of memory media, and at least one of the plurality of memory media can include a quarantined location (e.g.,  207 - 1 ,  207 - 2 , and/or  207 - 3 ) and a request to access data stored in the quarantined portion can be limited. The apparatus can further include a controller (e.g., host controller  209  and/or controller  210 ) coupled to the plurality of memory media, and the controller can be configured to receive image data and write the image data to the quarantined location of the at least one of the plurality of memory media. The controller can be further configured to reject a request to transfer the image data out of the apparatus such that the image data is refrained, while the image data is allowed to be transferred within the apparatus, from being transferred out of the apparatus. Stated differently, the image data that is stored in a quarantined location (e.g.,  207 - 1 ,  207 - 2 , and/or  207 - 3 ) can be allowed to be transferred to other (e.g., quarantined locations of) memory media, controller  210  and/or host  202 , but can be refrained from being transferred out of the computing system  201 . 
     In contrast to data stored in the quarantined location, data stored in a non-quarantined location can be not refrained (e.g., allowed) from being transferred out of the apparatus. Various types of settings can be pre-established (e.g., with respective pre-established thresholds) and applied to data received at the controller. For example, absent an indication that the image data is to be stored in the non-quarantined location, the image data received at the controller can be automatically transferred to and stored in the quarantined location of the at least one of the plurality of memory media. For example, absent an indication that the image data is to be stored in the quarantined location, the image data received at the controller can be automatically transferred to and stored in the non-quarantined location of the at least one of the plurality of memory media. 
     In some embodiments, the controller can be configured to write the image data to the quarantined location of the at least one of the plurality of memory media in response to one or more attributes of the image data being less than a threshold. As described herein, new settings can be generated and/or thresholds of existing settings can be altered. For example, the controller can be configured to receive one or more inputs indicating whether the image data with the one or more attributes is to be stored in the quarantined location or non-quarantined location of at least one of the plurality of memory media. The controller can be further configured to identify a pattern underlying the one or more inputs, and adjust the threshold based on the pattern. 
       FIG.  3    is a diagram of a memory system  304  including multiple memory media types coupled to a host  302  in the form of a mobile device in accordance with a number of embodiments of the present disclosure. The host  302  can include a host controller  309  which can be analogous to the host  102  and host controller  109  respectively described in connection with  FIG.  1   . The host  302  can be communicatively coupled to image sensors in the form of a front camera  330 - 1  and a back camera  330 -N which can be generally referred to as the cameras  330  and be analogous to image sensor  230  described in connection with  FIG.  2   . 
     The host  302  can include a memory system  304  which can be analogous to memory system  104  described in connection with  FIG.  1    and include multiple memory media types. As illustrated in  FIG.  3   , the memory system  304  can include memory media, such as memory media  312  including control circuitry  313  and an array of DRAM memory cells  305 - 1 , memory media  314  including control circuitry  315  and array of SCM memory cells  305 - 2 , and memory media  316  including control circuitry  317  and array of NAND memory cells  305 - 3  that can be analogous to memory media  112 ,  114 , and  116 , respectively, as described in connection with  FIG.  1   . 
     At least one of the plurality of memory media can include a quarantined location. As a non-limiting example as illustrated in  FIG.  3   , the array of each memory media can include a quarantined location. For example, the memory media  312 ,  314 , and  316  can include quarantined locations  307 - 1  (included within the DRAM array  305 - 1 ),  307 - 2  (included within the SCM array  305 - 2 ), and  307 - 3  (included within the NAND array  305 - 3 ), respectively. Although  FIG.  3    illustrates that a quarantined location is located as a portion of each memory media  312 ,  314 , and  316 , various and/or different locations of the memory media  312 ,  314 , and/or  316  can be configured as a quarantined location. For example, one of the memory media  312 ,  314 , and/or  316  can include a quarantined location, while other memory media  312 ,  314 , and/or  316  do not include. For example, unlike how it is illustrated in  FIG.  3   , in which only a portion of the memory media is configured as a quarantined location, the entire memory media can be configured as a quarantined location. 
     The example host  302  is in the form of a mobile device (e.g., an IoT enabled device). An IoT enabled device can include mobile phones, smart phones, tablets, phablets, computing devices, implantable devices, vehicles, home appliances, smart home devices, monitoring devices, wearable devices, devices enabling intelligent shopping systems, among other cyber-physical systems. The cameras  330  can include multiple types of cameras (e.g., video or static) located on the mobile device host  302 . The location and/or operation of the cameras  330  can be an attribute of the image data and be used to generate a setting. For example, image data (e.g., photographs) generated by the front camera  330 - 1  may have similar or different settings than the back camera  330 -N. 
     For example, a user of the mobile device  302  may provide different input about photographs generated from the front camera  330 - 1 . A photograph generated from the front camera  330 - 1  may be a photograph taken by the user of the user (e.g., a selfie) that the user does not desire that to be exposed to a public. Accordingly, a user may decide to store the photograph generated from the front camera  330 - 1  in one of quarantined locations  307 - 1 ,  307 - 2 , and/or  307 - 3  of the memory media  312 ,  314 , and/or  316 . In contrast, photographs taken by the back camera  330 -N may elicit different input. For example, photographs generated from the back camera  330 -N may be of people, nature scenery, animals, object, etc. that the same user may not mind sharing the photographs to the public. Accordingly, a user may decide to store the photograph generated from the back camera  330 -N in one of non-quarantined locations  307 - 1 ,  307 - 2 , and/or  307 - 3  of the memory media  312 ,  314 , and/or  316 . Such a pattern derivable from those inputs can be applied by the host controller  309  and/or controller  310  such that the photograph taken by the front camera  330 - 1  can be automatically stored in one of the quarantined locations, while the photograph taken by the back camera  330 -N can be automatically stored in one of the non-quarantined locations. Stated differently, a threshold of a setting applicable to data obtained via one sensor can be different from a threshold of the setting applicable to data obtained via another sensor. 
     The host controller  309  and/or the controller  310  can apply multiple settings to photographs (e.g., image data) received from one or more cameras  330  (e.g., image sensors). For example, a first setting can include a first threshold, and responsive to receiving a first image from one or more cameras  330  (e.g., images sensors) the host controller  309  and/or the controller  310  can determine if the first image is above or below a first threshold corresponding to the first setting. If the first image has attributes that are above the first threshold corresponding to the first setting, the host controller  309  and/or the controller  310  can write the first image to a non-quarantine location of memory media  312 ,  314 , and/or  316 . If the first image is below the first threshold corresponding to the first setting, the host controller  309  and/or the controller  310  can write the first image to a quarantined location of the memory media  312 ,  314 , and/or  316 . 
     Continuing with the previous example, a second setting can include a second threshold, and responsive to receiving a second image from one or more cameras  330  (e.g., images sensors) the host controller  309  and/or the controller  310  can determine if attributes of the second image is above or below a second threshold corresponding to the second setting. If the second image has attributes that are above the threshold corresponding to the second setting the host controller  309  and/or the controller  310  can write the second image to a non-quarantined location of the memory media  312 ,  314 , and/or  316 . If attributes of the second image are below the second threshold corresponding to the second setting the host controller  309  and/or the controller  310  can write the second image to a quarantined location of the memory media  312 ,  314 , and/or  316 . 
     These settings can operate in combinations thereof. For example, the host controller  309  and/or controller  310  can determine to write single image data to a quarantined location of the memory media  312 ,  314 , and/or  316  unless the single image data satisfies all of multiple settings applied to the single image data (e.g., attributes of the single image data being above of all thresholds of multiple settings). As described herein, access to data stored in the quarantined location, such as quarantined locations  307 - 1 ,  307 - 2 , and/or  307 - 3  can be entirely refrained and/or limited which can refrain applications (e.g., that may have been granted permission to access the data) from accessing the data stored in the quarantined location and protect the data against the undesirable exposure to a public. 
     In other embodiments, the host controller  309  and/or the controller  310  can refrain from writing the image data (e.g., deleting the image data) to a particular memory media type (e.g., memory media  312 ,  314 , and/or  316 ) to be potentially deleted from the mobile device  302  responsive to review by a user. For example, the host controller  309  and/or the controller  310  can apply one or more settings to a plurality of photographs generated from one or more cameras  330 . The plurality of photographs can be written as described above to particular memory media types based on the thresholds of the applied settings, and responsive to a determination that the attributes of a portion of the plurality of photographs are not desired the host controller  309  and/or the controller  310  can write the data to a particular memory media type (e.g., NAND  316 ) to be reviewed by a user of the mobile device  302  for deletion. 
       FIG.  4    is a flow diagram  439  of a method for accessing data stored in quarantined memory media in accordance with a number of embodiments of the present disclosure. At  440 , data can be received at a memory system (e.g., memory system  104 ,  204 , and/or  304  as described in connection with  FIGS.  1 ,  2 , and  3   , respectively). As described herein, the memory system can include a plurality of memory media having various types, and at least two of the plurality of memory media can be different types of memory media (e.g., DRAM, SCM, and/or NAND as described in connection with  FIGS.  1 ,  2   , and/or  3 ). 
     At  442 , one or more attributes of the data received at the memory system can be identified, for example, by a controller. The controller can be analogous to a controller such as controller  110 ,  210 , and/or  310  as described in connection with  FIGS.  1 ,  2 , and  3   . As described herein, the attributes identified by the controller can be compared to threshold(s) of one or more settings. 
     At  444 , the data can be written, in response to the one or more attributes of the data being identified, to an address range corresponding to a particular location (e.g., of the plurality of memory media) that is quarantined (also referred to as a quarantined location). As described herein, the particular location is quarantined in a sense that a request to access data stored in the quarantined location is limited. Accordingly, at  446 , even when a request to transfer the data out of the memory system is received (e.g., at the controller), the data can be refrained from being transferred out of the memory system since the data is written to the quarantined location of the plurality of memory media. For example, the data can be refrained from being uploaded to a social networking service (SNS) and/or being (e.g., automatically) synchronized on a cloud system. 
     In some embodiments, although the data written to the quarantined location may still be refrained from being transferred out of the memory system, the data can be allowed to be transferred within the memory system. For example, the data written to the quarantined location can be transferred to another location within a same memory media and/or different media, and/or different components such as control circuitry, controller, and/or a host controller. 
     In some embodiments, the controller can determine, based on attributes of data, the data to be written to an address range corresponding to a different location that is not quarantined (also referred to as non-quarantined location). In response to receiving a same request (e.g., request to access transfer the data out of the memory system), the data can be allowed to be transferred out of the memory system. 
       FIG.  5    is a flow diagram  549  of a method for accessing data stored in quarantined memory media in accordance with a number of embodiments of the present disclosure. At  550 , first image data and second image data can be received by a memory system (e.g., memory system  104 ,  204 , and/or  304  as described in connection with  FIGS.  1 ,  2 , and  3   , respectively). As described herein, the memory system can include a plurality of memory media having various types and at least two of the plurality of memory media can be different types of memory media (e.g., DRAM, SCM, and/or NAND as described in connection with  FIGS.  1  and  2   ). In this example, the first image data is received while the memory system is in a first operation mode, and the second image data is received while the memory system is in a second operation mode. 
     At  552 , the first image data that is received while the memory system is in the first operation mode can be written to an address corresponding a first location of the plurality of memory media. At  554 , the second image data that is received while the memory system is in the second operation mode can be written to an address range corresponding to a second location of the plurality of memory media. The second location where the second image data is or is to be written to can be quarantined (e.g., a quarantined location) such that a request to access data stored in the second location is limited. Accordingly, in response to receiving a request to transfer the second image data out of the memory system, the second image data can be refrained from being transferred out of the memory system. In contrast, in response to receiving a request to transfer the first image data out of the memory system, the first image data can be allowed to be transferred out of the memory system. 
     Although specific embodiments have been illustrated and described herein, those of ordinary skill in the art will appreciate that an arrangement calculated to achieve the same results can be substituted for the specific embodiments shown. This disclosure is intended to cover adaptations or variations of one or more embodiments of the present disclosure.
