摘要：According to one embodiment, a memory management device includes ahistory management unit, an address translation table, an address management unit, and

a data management unit. The history management unit manages an access history fordata stored in a nonvolatile semiconductor memory. The address translation tableincludes a translation table of a logical address and a physical address corresponding tothe data. The address management unit specifies, based on the access history, seconddata to be accessed after access to first data being stored in the nonvolatile

semiconductor memory, and registers a second physical address corresponding to thesecond data in the address translation table in association with a first logical addresscorresponding to the first data. The data management unit reads out the second datafrom the nonvolatile semiconductor memory to a buffer.
