INFORMATION PROCESSING APPARATUS INCLUDING MEMORY MANAGEMENT DEVICE, AND MEMORY MANAGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To effectively use a nonvolatile memory which is limited in rewrite frequency or read frequency. SOLUTION: The information processing apparatus including a memory management device 1 includes: an accepting means 18 which accepts a write destination logical address and write target data from a processor 6, the write destination logical address indicating a write position to write the write target data into a hybrid memory 2 which includes a first memory 8 and a nonvolatile second memory 9; an address determination means 19 which determines a write destination physical address corresponding to the write destination logical address so that the number of times of access to the second memory 9 is smaller than the number of times of access to the first memory 8; an address management means 20 which stores, in a storage means 17, address conversion data 13 associating the write destination logical address with the write destination physical address; and a writing means 21 which writes the write target data into a position in the hybrid memory 2 indicated by the write destination physical address.
