semiconductor memory

Abstract

Abstract PURPOSE:To decrease the level of current consumption, by using a control means which contains the decoders, memory cells, sense amplifiers and output buffers and drives selectively the output buffer with an address data. CONSTITUTION:The memory cell groups 4 storing data in corresponding to prescribed bit, plural sense amplifiers 5 which detect the data given from the memory cells, and the output buffer groups 6 that detect the detection data are provided at both sides of a line decoder 1 and a row decoder 2 that receive the address data and designate the prescribed address. The buffer group 6 is selectively driven with the address data and delivers the data given from a memory cell designated by the decoder through the group 6 which is selectively driven. Thus the current flowing to a load circuit 7 is limited to a right or left half. As a result, the level of current consumption is greatly decreased.
