Abstract

PURPOSE:To secure the power-down state with every nonselection block and thus ensuring the low power consumption even when the chip is selected, by forming the memory into blocks in a semiconductor memory chip and then providing the power-down element at the memory block decoder part. CONSTITUTION:The X decoders 21-24 and the memory matrices 11-14 are divided into four memory blocks 211-214, and then the memory block selection/nonselection circuit 22 is actuated by the addresses A1 and A2 to select the memory blocks. The circuit 22 delivers the output to the Y decoders 21-22 and supplies the power- down signal to the blocks except for the selection block. Thus other blocks are set under the power-down state, and at the same time the X decoder 21 of the selected block is made active. Then the X selection is carried out by the addresses A3-A6; and the Y selection is done through the Y decoder 23 and by the addresses A7-A8 respectively.
