Power supply circuit for flip-flop memory

摘要

A memory device is disclosed which is automatically and stably set to a predetermined logic state upon the application of power thereto. The memory device comprises a flip-flop having first and second cross-connection points, a state setting transistor coupled between the second cross-connection point and a reference voltage terminal, a voltage detection circuit for detecting the value of a power supply voltage, and a reset circuit responsive to an output signal of the detection circuit for controlling the state setting transistor.
