Non-volatile latch circuit that has minimal control circuitry
摘要:
A non-volatile latch circuit that has minimal control circuitry is disclosed. The non-volatile latch circuit is typically used in applications where only several bits of data need to be stored in non-volatile memory. The non-volatile latch circuit can be programmed and read using three control signals: a programming voltage/supply voltage signal, a data in signal, and a read/{overscore (write)} signal. By using fewer control signals, the number of transistors used to implement the control circuitry within the non-volatile latch circuit is reduced and thus the non-volatile latch circuit consumes less chip area/volume on an integrated circuit device.
