Abstract
In a dynamic random access memory unit 10, a circuit, 61.sub.0 -61.sub.N.sbsb.--.sub.1, 615, and 617, is provided in which a non-change of each address signal of an address signal group during a next consecutive clock cycle blocks the application of the read activation control signal to the memory unit 10. In this manner, the memory unit 10 is inactive (i.e., does not perform a read operation) during the modify portion of a read-modify-write operation so that potential conflicts in the operation of the memory unit 10 are avoided.
