ABSTRACT:
A data memory system comprising a memory including a plurality of memory locations from which a stored data is readable and to which data is writable, an address latch for receiving and holding from an external device a relative address designating a memory location to be accessed, and an address decoder for designating an absolute address of a memory location of the plurality of memory locations on the basis of the relative address held in the address latch. This designated memory location is called an "m"th memory location. An address translation unit is controlled to change the "m"th memory location designated by the relative address to an "n"th memory location which is different from the "m"th memory location, where "m" and "n" are positive integers, based on the number of writes to the memory and the existence of coincident data in the "m"th and "n"th memory locations.
