Abstract
According to one embodiment, the device comprises an input part, a disc-shaped storage medium, a non-volatile memory which becomes a cache memory for the disc-shape storage medium, an acquisition part which acquires status information showing the status of the non-volatile memory, and a control part which outputs the status information acquired by the acquisition part based on a status request command input in the input part.
Claims11
An information storage device comprising:
- an input part configured to be input with a command, a disc-shaped storage medium, a non-volatile memory configured to become a cache memory for the above disc-shaped storage medium, an acquisition part configured to obtain a status information showing the status of the non-volatile memory, and a control part configured to perform writing information on the non-volatile memory based on a writing command input in the above input part, storing the information recorded in the non-volatile memory in the disc-shaped storage medium at a prescribed timing, and outputting a status information obtained in the above acquisition part based on a status request command input in the input part.
A host device comprising:
- a processing part configured to generate a status request command for requesting the control part to output a status information which the acquisition part has acquired, as for the information storage device having an input part configured to be input with a command, a disc-shaped storage medium, a non-volatile memory configured to become a cache memory for the disc-shaped storage medium, an acquisition part configured to acquire status information showing the status of the non-volatile memory, and a control part configured to perform writing information on the non-volatile memory based on a writing command input in the input part and storing the information recorded in the non-volatile memory in the disc-shaped storage medium at a prescribed timing.
A control method of an information storage device comprising:
- a first process in which a command is input, a second process in which information is written on a non-volatile memory which becomes a cache memory for the disc-shaped storage medium based on the writing command input in the first process, a third process in which the information recorded in the above non-volatile memory in the second process is stored in the above disc-shaped storage medium at a prescribed timing, a fourth process in which the status information showing the status of the non-volatile memory is obtained, and a fifth process in which the status information obtained in the fourth process is output based on a status request command input in the first process.
