FIGS. 1A and 1B are schematic diagrams of electronic devices 10 and 20, respectively, wherein each of electronic devices 10 and 20 includes a data processing apparatus 1000 according to certain exemplary embodiments. Electronic devices, such as electronic device 10 and electronic device 20, may include, for example, one or more of: stationary and/or portable computers, whether having single processors, multiple processors, or multi-core processors; workstations; mainframes; servers; clients; television; stationary or portable telephones or telecommunications devices; personal digital assistants (PDA); tablet computers; scanners; pagers; cameras; musical devices; etc. Electronic devices, such as electronic device 10 or electronic device 20, and data processing apparatus 1000 may include one or more of the following: processors or central processing units (CPUs) configured to execute computer program instructions to perform various processes and methods consistent with certain disclosed embodiments; random access memory (RAM) and/or read only memory (ROM) configured to access and store information and computer program instructions associated with the disclosed embodiments; memory or other storage devices to store data and information; databases to store tables, lists, or other data structures; input/output (I/O) devices; interfaces; antennas; etc.
In some embodiments, such as those illustrated in FIGS. 1A and 1B, the data processing apparatus 1000 may include an embedded memory 400, a memory card 200, a memory card socket 100 for accommodating the memory card 200, and software that controls the memory card socket 100. In some embodiments, the software may manage the controller 300 to control the memory card socket 100.
Referring to FIG. 1A, a smartphone is shown as an example of the electronic device 10 that includes the data processing apparatus 1000. In some embodiments, the electronic device 10 may include an operating system (OS). The OS may be installed on a memory device, and one or more processors or CPUs included in the data processing apparatus 1000 may be configured to execute the instructions thereby causing the OS to operate on the data processing unit 1000. In some embodiments, the embedded memory 400 and the memory card 200 device may be classified as one or more of a built-in memory and an external memory. Either one may be referred to herein as a memory device.
For example, the built-in memory may be the embedded memory 400, and the external memory may be the memory card 200. The embedded memory 400 may be provided directly in the electronic device 10 to configure a system of the electronic device 10, and a program that may control operations of the electronic device 10, such as an OS, may be installed in the embedded memory 400. The memory card 200 may provide additional storage space to complement and/or supplement limitations in a storage capacity of the embedded memory 400 and may for example, store data such as pictures, videos, etc.
Generally, manufacturing costs of the embedded memory 400 with respect to per unit storage capacity may be greater than those of the memory card 200. In addition, once a storage capacity of the embedded memory 400 is determined during the manufacturing process of the electronic device 10, the storage capacity may not be expanded at a later time. Therefore, because the memory card 200 may be used for the same purpose as the embedded memory 400, a number of benefits may be obtained.
In one aspect, from the perspective of a manufacturer of the electronic device 10, there may be improved inventory control and management when there is a reduced use of electronic devices 10 having the embedded memory 400 with a fixed capacity. For example, if the electronic devices 10 having the embedded memory 400 of a relatively smaller capacity have been manufactured but consumers prefer electronic devices having the embedded memory 400 of a relatively greater capacity, there may be problems in manufacture and inventory control and management. However, if the memory card 200 is used to compliment and/or supplement the embedded memory 400, as disclosed herein, the manufacturer may be able to provide electronic devices having the memory capacity desired by consumers.
In another aspect, from the perspective of a manufacturer of the memory card 200, the manufacturer may sell memory cards 200 in the retail market, allowing consumers to purchase additional memory cards 200 to enable a greater capacity for electronic devices, such as electronic device 10 and electronic device 20, thereby expanding the market for memory cards.
In addition, OSs different from an OS installed on the embedded memory 400 may be installed on the memory card 200. For example, an OS A may be installed on the embedded memory 400 to operate the electronic devices, such as electronic device 10 or electronic device 20. In addition, an OS B may be installed on the memory card 200, thereby providing to the user another OS that is configured to operate the electronic devices, such as electronic device 10 or electronic device 20. As a result, in some exemplary embodiments, totally different execution environments may be provided to the user to operate a single electronic device 10.
However, in certain embodiments, to enable use of the memory card 200 for the same purpose as that of the embedded memory 400, the memory card 200 cannot be isolated during the operation of the electronic device 10 or electronic device 20. For example, after the memory card 200 is inserted in a memory card socket 100 provided in the electronic device 10, if the memory card 200 is isolated from the memory card socket 100 (e.g., removed from the memory card socket 100) during the operation of the electronic device 10, unexpected errors may occur, e.g., data stored in the memory card 200 may be damaged or an error may occur in the system of the electronic device 10. When a program, such as the OS controlling the electronic device 10, is installed on the memory card 200, there may be even greater or more numerous errors.
Therefore, when using the memory card 200 for the same purpose as the embedded memory 400, it may be beneficial to provide a restriction that allows the memory card 200 to be isolated only when the electronic device 10 is not using the data on the memory card 200.
According to certain exemplary embodiments, the data processing apparatus 1000 may control the memory card socket 100 via a controller 300. For example, the memory card socket 100 may allow for the state of the memory card 200 to be in a detachable state upon a user input of predetermined commands that are acted upon by, for example, software or instructions executing on the electronic device 10 or the data processing apparatus 1000. The software or instructions may be configured to allow the electronic device 10 or the data processing apparatus 1000 to manage the controller 300. During operation of the electronic device 10, for example, the electronic device 10 or the data processing apparatus 1000 may control the memory card socket 100 so that the memory card 200 may not be physically detachable (e.g., the memory card 200 may be locked in place when in a particular state), and thus, the memory card 200 may not be detached arbitrarily or accidentally. In such embodiments, the memory card 200 may be used for the same or similar purposes as the embedded memory 400.
Referring to FIG. 1B, a smartphone is shown as an example of the electronic device 20 that includes the data processing apparatus 1000. In addition, the electronic device 20 of FIG. 1B may further include an auxiliary memory card 200S and an auxiliary memory card socket 100S. In some embodiments, the auxiliary memory card socket 100S may not be controlled by the same software controlling the memory card socket 100, but may instead be controlled by different software. Further, in some embodiments, the auxiliary memory card 2008 may not be used for the same purpose as the embedded memory 400 or the memory card 200, but may be used as a general memory card.
For example, the memory card 200 may provide a storage space in which a program controlling the electronic device 20, such as an OS, may be installed, together with the embedded memory 400, and the auxiliary memory card 200S may provide a storage space for storing more general types of data, e.g., photos, videos, etc., which may be less relevant to control of the electronic device 20. Other components may be the same as those of FIG. 1A, and thus, detailed descriptions thereof may be omitted.
FIGS. 2A, 2B, and 2C are plan perspective views of a data processing apparatus according to some exemplary embodiments.
Referring to FIG. 2A, exemplary embodiments of the memory card 200 and the memory card socket 100 forming the data processing apparatus 1000 are shown. For convenience of description, inside of the memory card socket 100 in which the memory card 200 is mounted is projected and generally shown. The memory card 200 may be inserted in a main body 110 of the memory card socket 100 through an insertion portion 130 of the memory card socket 100. Referring to FIG. 8, in some embodiments, a plurality of terminals 251 and 252 (e.g., external conductive terminals for communicating between internal circuitry of the memory card 200 and an outside of the memory card 200) may be formed on a surface of the memory card 200, and the memory card socket 100 may include socket terminals 151 and 152 corresponding to the plurality of terminals 251 and 252 to allow for socket terminals 151 and 152 to be electrically connected to the plurality of terminals 251 and 252, respectively. Referring to FIG. 1A, in some embodiments, the electronic device 10 may read and write data to and from the memory card 200 via the plurality of terminals 251 and 252 and the socket terminals 151 and 152.
Returning to FIG. 2A, a lock portion 120 may be formed on the memory card socket 100. The lock portion 120 may be positioned and configured to engage with a notch 220 formed on an edge of the memory card 200. In some embodiments, when the lock portion 120 is engaged with the notch 220 of the memory card 200, detaching of the memory card 200 may be prevented or inhibited. As such, the lock portion 120 may be referred to as a locking device, which may be in a locked state or an unlocked state.
The lock portion 120 may include a first element 120A (or first component), a second element 120B (or second component), and a rotary shaft 120C. In certain embodiments, the first element 120A may be configured to move by a predetermined angle and/or in a predetermined direction about the rotary shaft 120C. The first element 120A may be moved by, for example, an elastic body or the like.
Generally, the lock portion 120 may check whether the memory card 200 is mounted correctly in the memory card socket 100, and may prevent the memory card 200 from being isolated from the memory card socket 100 due to, for example, external shocks or abrupt jostling applied to the electronic device 10 during use or operation of the electronic, device 10.
In some embodiments, the lock portion 120 may include the first element 120A that may control attaching and detaching of the memory card 200, and the second element 120B that may be controlled according to the software. For example, the first element 120A may prevent the memory card 200 from being isolated from the memory card socket 100, and the second element 120B may be designed or configured to control movement of the first element 120A according to commands from the software. In certain embodiments, the software may be installed on the controller 300, while in other embodiments, the software may be installed elsewhere. This will be described in detail with reference to FIG. 2C.
When the lock portion 120 receives an unlock command from the software, the lock portion 120 may move freely, and the memory card 200 may be inserted to or removed from the memory card socket 100 according to user's intention. As shown in FIG. 2a, a direction in which the memory card 200 is inserted in the memory card socket 100 is denoted by an arrow. In embodiments where the lock portion 120 has received an unlock command, the electronic device 10 may not be performing operations involving the memory card 200, such as, for example, a read/write of data to/from memory card 200 or executing a programs, such as the OS, on the memory card 200. Therefore, in some embodiments, when the memory card 200 is removed from the memory card socket 100, the electronic device 10 may not be affected.
Referring to FIG. 2B, exemplary embodiments of the memory card 200 and the memory card socket 100 forming the data processing apparatus 1000 are shown. For convenience of description, inside of the memory card socket 100 in which the memory card 200 is mounted is projected and generally shown.
The lock portion 120 of the memory card socket 100 may include the first element 120A controlling the attaching and detaching of the memory card 200, and the second element 120B controlled by the software, as described above in connection with FIG. 2A. The first element 120A and the second element 120B may be physically and/or communicatively coupled to each other. If a recess is formed in a part of the first element 120A and the second element 120B is engaged with the recess of the first element 120A, the first element 120A may be maintained in a fixed state. In some embodiments, when the first element 120A is in a fixed state, the first elements 120A may not be moveable and, therefore, may be configured to prevent or inhibit the memory card 200 from being removed.
In some embodiments, the second element 120B may move back and forth in the direction of inserting the memory card 200 (i.e., up and down perpendicularly to the inserting direction of the memory card 200), thereby allowing the second element 120B to be inserted into or removed from the recess of the first element 120A.
Thus, in certain embodiments, when the second element 120B is inserted into the first element 120A according to a lock command instruction, the lock portion 120 may be maintained in a locked state. As a result, there may be a reduced ability to physically isolate the memory card 200 from the memory card socket 100 with a normal operation, and the electronic device 10 may be enabled to perform operations involving the memory card 200, such as, for example, a read/write of data to/from the memory card 200 or executing programs such as the OS on the memory card 200. In embodiments where the memory card 200 is not removed from the memory card socket 100 according to the user's intention or according to the necessity, the electronic device 10 may use the memory card 200 as a memory device for the same or similar purpose as that of the embedded memory 400.
FIG. 2C shows an expanded view of the lock portion 120 of the memory card socket 100, consistent with certain disclosed embodiments. The lock portion 120 may include the first element 120A, the second element 120B, and the rotary shaft 120C. The first element 120A may be engaged with the notch 220 on the edge of the memory card 200 or directly with the edge of the memory card 200 to prevent the memory card 200 from detaching from the memory card socket 100. The second element 120B may be physically coupled or connected to the first element 120A when the lock portion 120 is locked according to the lock command instruction, and may be separated or uncoupled from the first element 120A when the lock portion 120 is unlocked. In some embodiments, the first element 120A may include the rotary shaft 120C. The rotary shaft 120C may guide or control the first element 120A, such that the first element 120A moves in a constant direction. The constant direction may be, for example, a horizontal direction, a vertical direction, an arced direction toward and away from the memory card 200, etc. The first element 120A may be designed to move in the constant direction when receiving a force or pressure from, for example, an elastic body or the like. In some embodiments, the lock portion 120 may be located near an edge of the insertion portion 130 of the memory card socket 100.
In certain embodiments, the software configured to control a part of the data processing apparatus 1000 may be further configured to control the second element 120B. Moreover, in some embodiments, the second element 120B may be moved by an actuator (not shown).
FIGS. 3A, 3B, and 3C are graphic representations illustrating example screen shots of a data processing apparatus according to some exemplary embodiments.
FIG. 3A shows an illustrative main screen 310 displaying a status of the software controlling a lock portion 120 of a memory card socket 100 in the data processing apparatus 1000. In some embodiments, the software may include instructions that, when executed by one or more processors or CPUs, may control the controller 300 of the electronic device 10. In some exemplary embodiments, such as when the electronic device 10 is a smart phone, the software may be a mobile application installed on and executed by one or more components of the smartphone. The software may be configured to control, store, retrieve, transmit, execute or act upon various pieces of information related to the electronic device 10. In the example embodiment of FIG. 3A, when the software instructions are being executed, the main screen 310 of an electronic device 10 may present or display to the user a lock command icon 312 and an unlock command icon 314. If the electronic device 10 includes a touchscreen, such as, for example, touchscreens found in smartphones, computing devices, vehicle displays, etc., the lock command icon 312 and the unlock command icon 314 may be touched by a finger or the like to cause the electronic device 10 to execute the command and/or instructions associated with the respective the lock command icon 312 and the unlock command icon 314. If the electronic device 10 includes an auxiliary input device (e.g., keyboard, microphone, mouse, etc.), the lock command icon 312 and the unlock command icon 314 may be selected (e.g., mouse click, keyboard shortcuts or arrows, voice recognition) to cause the electronic device 10 to execute the command and/or instructions associated with the respective the lock command icon 312 and the unlock command icon 314.
In some embodiments, the lock command icon 312 and the unlock command icon 314 may be arranged in parallel or arranged diagonally on the main screen 310. The lock command icon 312 and the unlock command icon 314 may be of a different color or different color combinations from each other for improving visibility. Additionally or alternatively, the lock command icon 312 and the unlock command icon 314 may have different patterns from each other for improving visibility. The lock command icon 312 and the unlock command icon 314 may include identifiable language (e.g., “lock,” “unlock,” etc.) or symbols (e.g., an open lock symbol, a closed lock symbol, etc.).
FIG. 3B shows an illustrative locked state Screen 320 displayed on a screen of an exemplary electronic device 10 in order to notify the user of the current state. FIG. 3B represents embodiments in which the user touches or clicks the lock command icon 312 on the main screen 310. In some embodiments, a locked state display 322 displayed on the locked state screen 320 may have the same color, combination of colors, and/or patterns as that of the lock command icon 312 so that the user may intuitively recognize the state of the data processing apparatus 1000. In certain embodiments, an audio or visual alarm, alert or other notification, a vibration, or a voice notifying the user of the locked state may be provided on or through the locked state screen 320, as well as the locked state display 322, according to a setting of the user. After displaying the locked state screen 320 on the screen of the electronic device 10 for a predetermined time period, the software that is executing may be automatically terminated or manually terminated by the user. When the locked state screen 320 is displayed on the screen of the electronic device 10, the lock portion 120 of the memory card socket 100 may be locked. When the lock portion 120 has been in the locked state, the locked state may be maintained continuously, and if the lock portion 120 has been in an unlocked state, the lock portion 120 may be switched to the locked state.
As illustrated above with reference to FIG. 2C, when the lock command is issued the locked state screen 320 may be displayed on the screen of the electronic device 10, and the second element 120B of the lock portion 120 may be coupled to the first element 120A. As shown in FIG. 1A, since the memory card socket 100 mounted in the electronic device 10 may be installed on the electronic device 10, it may be difficult for the user to check the operating state of the memory card socket 100 without separating a cover of the electronic device 10. Therefore, it may be beneficial to notify the user of the current operating state of the memory card socket 100. For example, an audio or visual alarm, alert or other notification, a vibration, or a voice may be used to notify the user of the locked state. In some embodiments, a visual notification may be displayed on the screen of the electronic device 10. By providing the locked state screen 320 to the user, for example, the user may identify the current operating state of the data processing apparatus so as not to forcibly or unintentionally remove the memory card 200 from the memory card socket 100 when the memory card 200 is in use.
FIG. 3C shows an unlocked state screen 330 that may be displayed on the screen of the electronic device 10 to notify the user of the current state. In some embodiments, the unlocked state screen 330 may be displayed when the user touches or clicks the unlock command icon 314 on the main screen 310 of the electronic device 10. The unlocked state screen 330 may be generated by software executing on electronic device 10 or memory card 200 in response to, for example, the user touching or clicking on the unlock command icon 314. An unlocked state display 332 shown on the unlocked state screen 330 may have the same color, the same color combinations, or the same pattern as that of the unlock command icon 314 so that the user may intuitively recognize the state of the data processing apparatus. In some embodiments, an audio or visual alarm, alert or other notification, a vibration, or a voice may be used to notify the user of the unlocked state may be provided on or through, for example, the unlocked state screen 330, as well as the unlocked state display 332, according to a setting of the user. In certain embodiments, the audio or visual alarm, alert or other notification, the vibration, or the voice provided in connection with the unlocked stated may be different from the audio or visual alarm, alert or other notification, the vibration, or the voice provided in connection with the locked state. In some embodiments, after outputting and displaying the unlocked state screen 330 for a period of time on the screen of the smartphone, the software executing on electronic device 10 and/or memory card 200 may be automatically terminated or manually terminated by the user. Referring to FIG. 1B, in some embodiments, if the user touches or clicks the unlock command icon 314 on the screen of the smartphone, the data on the memory card 200 may be transferred to the embedded memory 400 or the auxiliary memory card 200S. When the transfer of the data from memory card 200 is finished, the unlocked state screen 330 may be displayed on the screen of the electronic device 10, and correspondingly, the lock portion 120 of the memory card socket 100 may be unlocked. If the lock portion 120 has been in the unlocked state, the unlocked state may be maintained, and if the lock portion 120 has been in the locked state, the lock portion 120 may be switched to the unlocked state.
As illustrated above with reference to FIG. 2C, when the unlock command is issued and the unlocked state screen 330 may be displayed on the screen of the electronic device 10, the second element 120B of the lock portion 120 may be separated or uncoupled from the first element 120A, In the unlocked state, the electronic device 10 may not perform the read or write operation of important data and programs, such as the OS, on the memory card 200 before switching to the locked state again.
FIGS. 4A, 4B, and 4C are schematic diagrams of a host 500 and memory cards 200, 200S, and 400 of the electronic device including the data processing apparatus according to some exemplary embodiments.
FIG. 4A shows the host 500 and the memory cards 200 and 400. The host 500 may arrange the embedded memory 400 and the memory card 200 in parallel with each other so as to cause the embedded memory card 400 to store the important data and the program controlling the electronic device 10, such as the OS, and the memory card 400 to store programs and data having relatively lower importance. In this case, for example, when the memory card 200 is unexpectedly isolated from the memory card socket 100, the effects to the electronic device 10 may be minimized. In some embodiment however, the storage capacity of the embedded memory card 400 may not be expanded, and the different kinds of OSs that may be realized in the electronic device 10 may be limited.
FIG. 4B shows the host 500 and the memory card 200 and 400 of the electronic device including the data processing apparatus according to some exemplary embodiments. As illustrated in FIG. 4B, in some embodiments, the host 500 may arrange the embedded memory card 400 and the memory card 200 in series, so as to cause both the embedded memory card 400 and the memory card 200 to store the programs controlling the electronic device 10, such as the OS, and the other important data, and the memory card 200 to store the programs and data having relatively lower importance. In some embodiments, such as the embodiment illustrated in FIG. 1A, if the memory card 200 is unexpectedly isolated from the memory card socket 100, the electronic device 10 may be affected. Although the embedded memory card 400 may not be able to expand its storage capacity, the storage capacity available to the electronic device 10 may be expanded by using the memory card 200. In addition, an OS that is different from the OS installed on the embedded memory card 400 may be installed on the memory card 200 so that two kinds of OSs may operate in the electronic device 10. Further, in some embodiments, because the embedded memory 400 and the memory card 200 communicate with each other and the host 500 and the memory card 200 communicate with each other, a data processing speed may be improved.
In certain embodiments, the electronic device 10 may recognize the memory card 200 and the embedded memory 400, which may be two separate storage spaces physically, as one combined storage space logically. In other embodiments, the electronic device 10 may recognize the memory card 200 and the embedded memory 400, that are physically separate two storage spaces, logically as a first storage space, including the embedded memory 400 and some of the storage space of the memory card 200, and a second storage space, including the remaining storage space of the memory card 200.
FIG. 4C shows the host 500 and the memory devices (i.e., memory device 200, memory device 200S, and memory device 400) of the electronic device including the data processing apparatus according to some exemplary embodiments. In some embodiments, the host 500 may arrange the embedded memory 400 and the memory card 200 in series so as to command both the embedded memory 400 and the memory card 200 to store software or instructions that control the electronic device 20 such as the OS and important data, and cause the auxiliary memory card 200S to store programs and data that may have relatively lower importance. Although the physical storage capacity of the embedded memory 400 may not be expanded, the storage capacity may be expanded logically by using the memory card 200. In addition, in some embodiments, a different kind of OS may be installed on the memory card 200 from the OS installed on the embedded memory 400 so that two kinds of OSs may operate in the electronic device 20. Also, the host 500 may command the auxiliary memory card 200S to store programs and data having relatively lower importance.
FIGS. 5A and 5B are a cut perspective view and a plan perspective view, respectively, of a data processing apparatus according to some exemplary embodiments.
FIG. 5A shows an example process of inserting the memory card 200 into the main body 110 via the insertion portion 130 of the memory card socket 100. In order to insert the memory card 200 into the main body 110 via the insertion portion 130 of the memory card socket 100, in some embodiments, the data processing apparatus 1000 may be in an unlocked state. When the data processing apparatus 1000 is in the unlocked state, the first element 120A and the second element 120B of the lock portion 120 may not be connected or coupled to each other, and thus, the first element 120A may rotate by a predetermined angle about the rotary shaft 120C. A surface of the main body 110, on which the lock portion 120 is located, may have a recess 115 for accommodating the first element 120A that is rotating. Therefore, in some embodiments, even when the first element 120A rotates, the first element 120A may be configured such that it does not protrude out of the memory card socket 100, and a radius of the rotation of the first element 120A may be within a predetermined angle range.
In some embodiments, when the data processing apparatus is in an unlocked state, the memory card 200 may be inserted into the memory card socket 100. At least one surface of the insertion portion 130 may have a different appearance from that of the main body 110 (e.g., a different color, a different set of colors, different pattern, etc.). In some embodiments, the appearance (e.g., color(s), pattern(s), etc.) of the insertion portion 130 may be highly visible, and may be complementary with the appearance of the main body 110 of the memory card socket 100 and the appearance (e.g., color(s), pattern(s), etc.) of a main board of the electronic device 10 in which the memory card socket 100 is inserted and/or mounted. In certain embodiments, the appearance of the insertion portion 130 may allow for the user to intuitively recognize when the memory card 200 is not completely inserted and mounted in the memory card socket 100. For example, if the memory card 200 is not completely inserted in the main body 110, the insertion portion 130 may be hidden by a part of the memory card 200 so that the color(s) or pattern(s) of the insertion portion are not visible. In such embodiments, the user may be prevented from instructing, the software to move to the locked state. Therefore, there may be a reduction in errors of the memory card socket 100 and the electronic device 10 due to the execution of the lock command when the memory card 200 is not properly inserted or mounted.
The above process also may be applied to the process of removing the memory card 200 from the memory card socket 100, as well as the process of inserting the memory card 200 in the memory card socket 100.
FIG. 5B illustrates an embodiment in which the memory card 200 is completely inserted in the memory card socket 100. As illustrated above with reference to FIG. 5A, in some embodiments, when the memory card 200 is inserted in the main body 110 via the insertion portion 130 of the memory card socket 100, the insertion portion 130 may be hidden by a part of the memory card 200 and the color(s) or pattern(s) of the insertion portion 130 may not be seen. However, as shown in FIG. 5B, in embodiments in which the memory card 200 is completely inserted into the main body 110 of the memory card socket 100 and mounted in the memory card socket 100, the edge of the memory card 200 or the notch 220 formed at the edge of the memory card 200 may be engaged with the lock portion 120 of the memory card socket 100, and the color(s) and pattern(s) of at least one surface of the insertion portion 130 may be completely visible. In some embodiments, the user may visibly identify whether the memory card 200 is fully inserted and mounted in the memory card socket 100 and whether the memory card 200 exists in the memory card socket 100, and thereby reduce the possibility of an unintentional or forcible removal of the memory card 200 from the memory card socket 100. In certain embodiments, when the memory card 200 is fully inserted and mounted in the memory card socket 100, the lock command may be executed automatically or manually by the user. When the memory card 120 is in the locked state, in some embodiments, the electronic device 10 may perform the read or write operation of relatively more important data or the OS on the memory card 200.
In some embodiments, at least one surface of the insertion portion 130 may be formed to project varying colors by using, for example, light emitting devices. The insertion portion 130 may be configured, in some embodiments, such that it emits light of varying colors, and the emitted colors may depend on whether or not the memory card 200 is inserted into the memory card socket 100. For example, if the memory card 200 is not fully inserted into the memory card socket 100, the light emitting device may emit blue light and may indicate a phrase such as “no card” or the like. As another example, if the memory card 200 is fully inserted and mounted in the memory card socket 100, the light emitting device may emit red light and may indicate a phrase such as “card exists” or the like. In some embodiments, the phrases (e.g., “no card”, “card exists”, etc.) may be displayed on a screen of the electronic device 10 or may be displayed via the light emitting, devices on the insertion portion 130. The light emitting devices may be independently controlled or may be controlled in association with the data processing apparatus 1000.
In some embodiments, the processes of inserting and coupling the memory card 200 to the memory card socket 100 and decoupling and removing the memory card 200 from the memory card socket 100 may include five stages. For example, the user may couple the memory card 200 to the memory card socket 100, the user may initiate the lock command and cause the electronic device to execute the lock command, the electronic device 10 may perform the read or write operations of relatively more important data and the OS on the memory card 200, the user may initiate the unlock command and cause the electronic device to execute the unlock command, and the user may remove the memory card 200 from the memory card socket 100.
An example process of inserting and coupling the memory card 200 to the memory card socket 100 may be as follows. When the user physically pushes the memory card 200 into the memory card socket 100 via the insertion portion 130, the electronic device 10 may recognize the memory card 200 and initiate the change to the lock command state. In some embodiments, the lock portion 120 of the memory card socket 100 may draw in or pull the memory card 200 so that the memory card 200 may be fully inserted into the main body 110 of the memory card socket 100, and the first element 120A may rotate such that it forms a hook that is fixed at a lower corner of the memory card 200. Then, the memory card 200 may be in the locked state such that the memory card 200 may not be physically unlocked. Therefore, in some embodiments, the locked state may be reached automatically after insertion of the memory card 200.
As described above, in some embodiments, the insertion portion 130 may have different colors or patterns from those of other elements or may include the light emitting devices so that the user may visibly identify when the memory card 200 is in the locked state. As such, the user may not unintentionally or forcibly remove the memory card 200 from the memory card socket 100 while it is in the locked state.
An example process of decoupling and removing the memory card 200 from the memory card socket 100 may be as follows. In some embodiments, the memory card 200 may be configured such that it may be prevented from being physically removed unless there is the unlock command from the electronic device 10. Thus, in some embodiments, the user may be provided with information related to the process for unlocking the memory card 200, and an improved ability to ensure reliability of the data stored on the memory card 200 and for terminating normally the system of the electronic device 10 before the unlock command is executed.
To issue the unlock command, in some embodiments, a memory card lock control application, may be used. For example, a memory card lock control application may begin the process of switching to the unlocked state when the user touches or clicks the unlock command icon 314, such as the unlock command icon displayed on electronic device 10 of FIG. 3A. After the memory card 200 is moved from inside of the memory card socket 100 to outside of the memory card socket 100, the user may pull the memory card 200 manually to remove the memory card 200 from the memory card socket 100 while unlocking the lock portion 120 at the lower corner of the memory card 200, thereby allowing the memory card 200 to enter the unlocked state. For example, the user may receive a message indicating the unlock process is finished via the alarm, alert or notification, the vibration, or the voice, and the user may remove the memory card 200 completely from the memory card socket 100 by, for example, pulling down a convex portion formed on a lower end of the memory card 200 or the lower end of the memory card 200.
As described above, since the insertion portion 130 may have different colors, patterns, or light emitting devices, the user may be notified visually of the unlocked state of the memory card 200. Thus, for example, errors that may occur when the user operates the electronic device 10 in the unlocked state may be minimized or prevented.
FIG. 6 is a plan perspective view of a data processing apparatus according to certain exemplary embodiments.
Referring to FIG. 6, in some embodiments, a latch unit 140 may be formed additionally on the main body 110 of the memory card socket 100. Although the latch unit 140 and the lock portion 120 are shown separately in FIG. 6, the latch unit 140 and the lock portion 120 may be formed, for example, as one elastic member. The memory card 200 may include a first notch 220 and a second notch 240 and the memory card socket 100 may include the lock portion 120 and the latch unit 140 so that the memory card 200 may be held or fixed in the memory card socket 100 via two portions. In some embodiments, the first notch 220 may be engaged with the lock portion 120 and the second notch 240 may be engaged with the latch unit 140, so that the memory card 200 may be firmly and stably inserted in the memory card socket 100 and mounted in the memory card socket 100.
In addition, in some embodiments, the lock portion 120 and the latch unit 140 may be formed on the same surface of the main body 110, or may be formed on different surfaces of the main body 110. Locations and shapes of the lock portion 120 and the latch unit 140 may be of varying designs depending on a shape and a standard of the memory card 200 within the scope of the disclosed embodiments. In some embodiments, the latch unit 140 may include an elastic member. For example, the latch unit 140 may be formed of the elastic member, or may partially include an elastic member therein.
FIG. 7 is a schematic view illustrating a system of the data processing apparatus 1000 according to certain exemplary embodiments.
Referring to FIG. 7, the system of the data processing apparatus 1000 may include the memory card socket 100, the memory card 200, the controller 300, and the host 500, such as those described above with reference to previous exemplary embodiments. The memory card socket 100 may be configured so that the memory card 200 may be inserted therein and may make contact with the memory card 200 and thereby to allow for the transfer of data to and from the memory card 200. For example, the memory card socket 100 may be electrically connected to the memory card 200. In some embodiments, the controller 300 may control data exchange with the memory card 200 via the memory card socket 100, and may control the locked state of the memory card socket 100. In certain embodiments, the controller 300 may be used also to store the data on the memory card 200. The controller 300 may, for example, be managed by the data processing apparatus 1000 and the software executing therein.
FIG. 8 is an example schematic diagram of the memory card socket 100, as disclosed above in connection with FIG. 7.
Referring to FIG. 8, in certain embodiments, the memory card socket 100 may be provided to allow for the memory card 200 to be inserted.
In some embodiments, the memory card socket 100 may include first row-corresponding socket terminals 151 corresponding to first row terminals 251 (e.g., external terminals) of the memory card 200, second row-corresponding socket terminals 152 corresponding to second row terminals 252 (e.g., external terminals) of the memory card 200, and the main body 110 accommodating the first row-corresponding socket terminals 151 and the second row-corresponding socket terminals 152.
Thus, for example, when the memory card 200 is inserted into the main body 110, the memory card 200 may contact the first row-corresponding socket terminals 151 and the second row-corresponding socket terminals 152.
The memory card socket 100 may be electrically connected to the controller 300, and power, signals, and/or data may be input to or output from the first row-corresponding socket terminals 151 and the second row-corresponding socket terminals 152.
A socket terminal may be included among the first row-corresponding socket terminals 151 and the second row-corresponding socket terminals 152. In some embodiments, the socket may be configured such that if a corresponding particular terminal of the inserted memory card 200 is a ground terminal, the memory card 200 may be recognized as a first card type, and if the corresponding particular terminal is a data terminal, the inserted memory card 200 may be recognized as a second card type. For example, based on the corresponding particular terminal, the first card type may be a universal flash storage (UFS) card, and the second card type may be a micro secure digital (SD) card. Examples of micro SD cards may include ultrahigh speed-1 (UHS-1) type or UHS-2 type.
The first row-corresponding socket terminals 151 may include several socket terminals so as to allow recognition of both the first and second card types. The second row-corresponding socket terminals 152 may also include socket terminals. In some embodiments, the number of second row-corresponding socket terminals 152 may be greater than that of the second row terminals 252, so as to allow recognition and use of different card types. The memory card socket 100 according to the disclosed embodiments, however, may not be limited to the number of the first and second row-corresponding socket terminals 151 and 152.
FIG. 9 is a schematic diagram of a memory card 2000 in the data processing apparatus according to some exemplary embodiments.
