Abstract
A storage device operates in host mode or device mode, and the storage device operating in host mode may transmit and receive various information units with the storage device operating in device mode to perform tests on the storage device operating in device mode, thereby performing the test of a storage device in development.
Claims19
A test system device comprising:
- a first storage device, operating in a host mode, including a first buffer memory and a first processor configured to create and store a command unit to test performance of a second storage device in the first buffer memory and to transmit the command unit to the second storage device, and configured to read and process a test input data unit received from the second storage device and stored in the first buffer memory;
- and
- the second storage device, operating in a device mode, including a second buffer memory and a second processor configured to read and process the command unit received from the first storage device and stored in the second buffer memory and configured to create and store the test input data unit corresponding to the command unit in the second buffer memory and to transmit the test input data unit to the first storage device,
- wherein the first storage device processes the test input data unit to check the performance of the second storage device.
1 more element
A controller comprising:
- a buffer memory;
- and
- a processor of a first storage device that operates in host mode or device mode and that is configured to, in the host mode, create and store a first command unit to test performance of a second storage device in the buffer memory and control the first command unit to be transmitted to a controller in the second storage device operating in the device mode,
- wherein, in the device mode, the processor of the first storage device reads and processes a test input data unit, received from the controller in the second storage device operating in the host mode, and stored in the buffer memory of the first storage device in the device mode.
1 more element
A storage device comprising:
- a memory including a plurality of memory cells;
- and
- a controller for controlling an operation of the memory,
- wherein the controller comprises;
- a buffer memory, and
- a processor operating in host mode or device mode and configured to, in the host mode, create and store a first command unit to test performance of another storage device in the buffer memory and control the first command unit to be transmitted to the another storage device operating in the device mode, or read and process a first test input data unit received from the another storage device operating in the device mode and stored in the buffer memory.
