Abstract
In a control register, tag address information which points at RAM areas defined in a data array is stored. A comparator compares a tag address of a cache access address with the tag address information stored in the control register and generates an access control signal which indicates that the RAM area defined in the data array of the cache memory is accessed according to the cache access address and which controls access to data in the RAM areas. As a result, RAM areas can be defined in arbitrary areas of the cache memory with treating the entry as a unit.
