ABSTRACT:
A programmable array logic circuit whose temporary memory circuitry employs single bit non-volatile ferromagnetic memory cells. The ferromagnetic memory cells or bits store data even when there is no power provided to the circuitry, thus saving power during operation of the programmable logic circuitry, and ensuring that there is no loss of the data should there be a temporary power shut down. Additionally, the ferromagnetic cells provide for indefinite number of switching actions on the data without degradation to the capacity to store data therein. The invention provides an integrated circuit, comprising a programmable logic circuit array having product lines and input lines therein, and a storage register circuit. The storage register circuit has a ferromagnetic bit and sensor coupled to store a remnant control signal and an output transistor, coupled to be responsive to the remnant control signal on its gate, and coupled between an input and product line. Additionally, the integrated circuit may further include a logical AND array and a logical OR array.
