Abstract
A dynamic-type memory A, a non-volatile memory B and a static-type memory C are enclosed in one package. Separated from a first terminal supplying a power-supply potential to the memories A and B, a second terminal supplying a power-supply potential to the memory C is provided. By stopping the supply of the power-supply potential to the first terminal at stand-by, stand-by current of a semiconductor memory device can be reduced. Therefore, the semiconductor memory device having an increased memory capacity while reducing a mounting area and consumption current at stand-by can be provided.
