ABSTRACT:
A programmable circuit and its method of operation are disclosed in which a transistor is used as a programmable element. The transistor may be programmed to one of two different gate threshold voltage values for operation. During reading of the transistor, a gate threshold voltage between the two values is applied and the status of the transistor as on or off is determined to determine the program state of the transistor. The program state of the transistor can be determined by a simple latch circuit.
