INFORMATION STORAGE DEVICE, MEMORY ACCESS CONTROL METHOD, AND COMPUTER PROGRAM

摘要

A device and a method in which before an unlocking processing is performed as a memory lock release processing, the locked state is maintained and reproduced after power is turned on again. In response to a command input through an information processing unit, an unlocking processing is performed as a memory lock release processing in an information storage device, such as a memory card, and locked state data before the unlocking processing is stored in a nonvolatile memory (NVM). When the information storage device which is off is turned on again, the memory locked state is reproduced based on the locked state data stored in the storage means, and memory access control is executed based on the reproduced locked state.
