ABSTRACT:
A compatible standby power driving circuit for a dynamic semiconductor memory includes a low impedance, high power driving circuit connected in parallel with a high impedance, low power driving circuit. The outputs of the high power and low power driving circuits are mutually connected to the column driving circuit output and the inputs of both driving circuits are connected to the refresh address selection line so that both the output of the high power driving circuit and the low power driving circuit are available under normal or regular power conditions and the low power driving circuit output is available under standby power conditions.
