Memory management device and method for managing access to a nonvolatile semiconductor memory

A memory management device comprising:

• a history management unit managing an access history for data stored in a nonvolatile semiconductor memory;
• an address translation table including a translation table of a logical address and a physical address corresponding to the data;
• an address management unit which specifies, based on the access history, second data to be accessed after access to first data being stored in the nonvolatile semiconductor memory, and registers a second logical address corresponding to the second data in the address translation table in association with a first logical address corresponding to the first data;
• and
• a data management unit which reads out the second data from the nonvolatile semiconductor memory to a buffer.
