Abstract
A semiconductor memory device of the present invention is so constituted that, in addition to a first address register for fetching and holding an address signal in synchronous with a clock signal irrespective of read operation and write operation, a second address register is provided to hold a write address, and an address selection circuit selects the held write address to write data held in an input data register into a cell. Thereby, a late write system can be achieved in an synchronous SRAM.
