Abstract

A MOS memory device operating at high speed which is so constructed as to hold the sense amplifier activating signals SAP and SAN at high potential and at low potential, respectively, even after the completion of a memory access, and keep the sense amplifier 30a in activated state to hold read data from memory cells. This memory device includes a block decoder which designates mutually different cell array blocks synchronized with a row selection signal RAS and a column selection signal CAS so that it is possible at the time of input of the column selection signal CAS to execute write/read operation in page mode that extends over the cell array blocks.
