Abstract
PURPOSE: To reduce the power consumption of the static type semiconductor memory unit, by conductive control of bit line load transistor with the column selection signal.
CONSTITUTION: The column selection signal is fed to the gate of bit line load transistors Q1, Q2... of enhancement type and the transistors Q1, Q2... are in conductive control with this signal. With this constitution, the transistors Q1, Q2... are used for only the memory cells C1, C2 selected with the selection signals Y1, Y2 and they are not required for the memory cells not selected, then the transistor to the selected cells C1, C2 only is ON and others are all OFF. Accordingly, the power consumption of memory unit can remarkably be reduced.
