Abstract

An N-word write access memory is described. Using a variation of conventional control signals RAS, CAS, WE and OE, an innovative scheme of signal protocol allows the N-bit word write memory to have an input/output bandwidth double that attained in the prior art, using substantially the same components and without affecting the bit-width, hence, the pin-count, of the external data bus.
