摘要 |
A bistable non-volatile latch circuit adapted to store a non-volatile binary data state during a program operation, and to assume one of two stable states in response to a recall operation that correspond uniquely to the data state has first and second circuit sections. The first circuit section has a first non-volatile current path with means to set the impedance of the first current path in a non-volatile manner. A first end of the first current path is connected to provide a logic output signal, which represents a binary logic state depending on a voltage applied to the a first signal input node. The set/reset signal to the first current path varies between at least the power source voltage and a program voltage that is negative with respect to the power source voltage. A second circuit section generates an output voltage on a second output node that represents a binary logic state opposite from the output states of the first circuit section. Means are provided for connecting the first circuit section and the second circuit section into a bistable configuration.
