Abstract

PURPOSE: To access data at a high speed by causing a dynamic RAM to act in a page mode when a column address is coincident with the storage contents of submemory.
CONSTITUTION: When a column address 1 is dissident with contents of a submemory 5, an output HIT20 of a comparator 6 becomes inactive, while a timing controller 9 becomes a random access mode to lead a low access strobe RAS to become continuously active. Then selected dynamic RAM modules 11a, 11b... are accessed at a high speed only by a row address. On the other hand, when they are coincident, the modules 11a, 11b... are brought into a page mode, and a dynamic RAM system is quickly accessed accordingly.
