[0003] The following description relates to a hybrid storage device, and an electronic system using the same
[0005] Devices having a serial advanced technology attachment (SATA) interface or a universal serial bus (USB) interface may use a port multiplier such as a hub to connect a plurality of slave devices to one host connector (port).

[0017] Power lines of the SATA interface device and the USB interface device may be commonly connected to a power supply pin in the SATA interface connector.
[0018] Power lines of the SATA interface device and the USB interface device may be commonly connected to a power supply pin in the SATA interface connector.
[0019] In yet another aspect, an electronic system is provided. The electronic system includes a hybrid storage device that includes a first storage part that includes an interface device based on a first standard, a second storage part that comprises an interface device based on a second standard, and a slave connector for interface devices that is shared by the first storage part and the second storage part and comprises a plurality of pins, a host connector that corresponds to the slave connector for interface devices, and a driving unit that drives the first storage part and the second storage part.

[0030] FIGS. 1 and 2 are views illustrating examples of a desktop computer and a notebook computer which are electronic systems using hybrid storage devices;
[0031] FIG. 3 is a diagram illustrating an example of a hybrid storage device;
[0032] FIG. 4 is a diagram illustrating an example of a hybrid storage device; and
[0033] FIG. 5 is a diagram illustrating an example of an electronic system.
[0036] The following description will now be described with reference to the accompanying drawings. Although an example of an optical disc drive (ODD) is used as a first storage device, the example is not limited thereto, and, for example, a solid-state storage device such as a magnetic storage device or a semiconductor memory may be used as a first storage device, instead.
[0037] FIGS. 1 and 2 illustrate examples of a desktop computer 10a and a notebook computer 10b which are electronic systems including hybrid storage devices 100a and 100b, for example hybrid ODDs. Drive bays 11a and 11b are respectively secured in the desktop computer 10a and the notebook computer 10b, and the hybrid storage devices 100a and 100b are inserted into the drive bays 11a and 11b, respectively.
[0038] The hybrid storage devices 100a and 100b may be connected to host devices such as the desktop computers 10a and the notebook computer 10b via interface cables (not shown) for transmitting signals. Examples of the host devices include computers having driving units for driving or controlling the hybrid storage devices 100a and 100b, and any electronic systems in which the hybrid storage devices 100a and 100b are installed. Meanwhile, an interface (slave) connector may be a serial advanced technology attachment (SATA) connector. The following example uses a SATA interface (slave) connector.
[0039] As shown in FIG. 3, each of the hybrid storage devices 100a and 100b includes a first storage part 110 such as an ODD and a second storage part 120 that is a non-optical storage part 120 that may be a solid-state storage device such as, for example, a solid state drive (SDD) or a flash memory. The first and second storage parts 110 and 120 include interface devices based on first and second standards. For example, the first storage part 110 includes a USB interface device (or structure), and the second storage part 120 includes a SATA interface device (or structure) based on a SATA standard. The first and second storage parts 110 and 120 including the interface devices based on different standards are connected to one interface connector 130 inserted into a printed circuit board (PCB) 101. Table 1 illustrates arrangements and functions of pins according to the SATA standard.

[0040] The interface connector 130 is an interface port connected to an electronic system for driving a hybrid storage device, such as, for example, the desktop computer 10a or the notebook computer 10b. The interface connector 130 is shared by the first storage part 110 and the second storage part 120 as shown in FIG. 4. Since one connector 130 is shared by the first and second storage parts 110 and 120, in order for the interface devices not to interfere with each other, data lines are connected to independent pins, which will be explained with reference to FIG. 5.
[0041] Referring to FIG. 5, in the interface connector 130, the first storage part 110 uses a device present (DP) pin, that is, an eighth pin, and a manufacturing diagnostic (MD) pin, that is, an eleventh pin, in the SATA standard for corresponding with D- and D+ pins (second and third pins, respectively) in the USB standard. The second storage part 120 may be a non-optical storage part such as an SDD that uses pins other than the eighth pin and the eleventh pin used by the first storage part 110. Ground pins GNDs and power supply pins VDDs may be commonly shared. For reference, in the USB standard, a fourth pin is a ground pin GND, a first pin is a power supply pin VBUS (or VDD) of 5 volts, and third and second pins are D+ and D- data pins, respectively.
[0042] Meanwhile, the desktop computer 10a and the notebook computer 10b respectively include interface circuits, that is, a USB interface circuit 12 and a SATA interface circuit 13, corresponding to the first storage part 110 and the second storage part 120. In other words, different medium devices include independent interface devices, host devices for driving the different medium devices also include different interface circuits and host connectors, and ground and power supply pins are commonly shared and connected.
[0043] An interface connector commonly shared by hybrid storage devices may be an interface connector based on a standard defining pins that may not be necessary in a SATA standard. In the SATA standard, an MD pin is a pin used by an ODD manufacturer, and a DP pin is a pin for determining the existence of a medium device and may not be necessary for actually driving the medium device. However, since such a connection structure does not completely meet requirements of the SATA standard, the hybrid storage devices are suitable for host devices correspondingly designed as described above.
[0044] Since different storage devices may be combined into a hybrid storage device, some problems, such as structural complexity, high cost, and low speed which may occur in response to different connectors being used or in response to one or the same type of interface connector being used with a multiplier, may be reduced.
[0045] Since different types of medium devices using different connectors to share one connector without using a multiplier (chip) may be used to connect a plurality of medium devices, product prices may be reduced. Since two different types of medium devices are connected to each other by using an interlace without using a multiplier are enabled, some of the problems of high power consumption and low data transfer rate which may occur in response to a multiplier being used may be reduced. In other words, two different types of medium devices may be used at low cost without reducing their performances.
[0046] It is understood that various changes in form and details may be made therein without departing from the spirit and scope of the following description as defined by the following claims.
[0047] A number of examples have been described above. Nevertheless, it will be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
