ABSTRACT:
A bistable latch circuit is disclosed which can be electrically programmed to be stable in only one of its two states so that this same state is always set when power is applied to the circuit. The circuit can be electrically reprogrammed at will to select either of its stable states, and it draws no dc current during either the program mode or read mode. During the read mode, the potentials on the circuit nodes are such that long data retention times are achieved.
