PROBLEM TO BE SOLVED: To provide a memory management device capable of easily constructing a memory access management system in a case where address spaces with different bit widths exist.SOLUTION: A memory management device includes: an access management module 21 for 32 bits that performs access management individually to a plurality of memory areas 27 in which a 64 bit space 15 with a relatively wide bit width is divided into 32 bits with a relatively narrow bit width; a cache 23 that holds an area management table T of the plurality of access management modules 21; and a dispatcher 25 that determines allocation of an access management module 21 with respect to a memory area 27 to be an access destination on the basis of the held area management table T, and enables the determined access management module 21 to access the memory area 27. |
