Abstract
A host apparatus, into which a card having a nonvolatile semiconductor memory is inserted, issues a check command to the card. The check command instructs to send information on whether the card supports a termination process in which the card shifts into a state ready for a stop of power supply from the host apparatus.
Claims7
A memory device connectable to a host device, the memory device comprising:
- a memory core;
- and
- a memory controller configured to:
- control the memory core,
- transmit, in response to a first command from the host device, a response of status data that is used to determine whether the memory device supports a termination process, the termination process including shifting into a state ready for a stop of power supply from the host device,
- perform the termination process in response to a second command from the host device,
- transmit a first signal indicative of a busy state while performing the termination process, the first signal being indicative of the busy state and having a first level, and
- notify the host device of completion of the busy state by transmitting a second signal indicative of a ready state and having a second level when the memory device completes the termination process and is ready for the stop of power supply to the memory device.
