Abstract
In a cache memory, a main unit stores memory address information which is associated with part of data stored in a memory space to be accessed, on a cache line-by-cache line basis. The memory space is divided into a plurality of memory regions. The address generation unit generates a cache memory address from a memory address specified by an external access request, based on a memory region among the plurality of memory regions which is associated with the memory address specified by the access request. A main unit is searched according to the cache memory address, thereby searching and replacing different ranges of cache lines for different memory regions.
