Abstract
According to one embodiment, a memory management device includes a history management unit, an address translation table, an address management unit, and a data management unit. The history management unit manages an access history for data stored in a nonvolatile semiconductor memory. The address translation table includes a translation table of a logical address and a physical address corresponding to the data. The address management unit 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 physical address corresponding to the second data in the address translation table in association with a first logical address corresponding to the first data. The data management unit reads out the second data from the nonvolatile semiconductor memory to a buffer.
