Abstract
An electrically programmable, non-volatile memory that can be used for the storage of the defective addresses in a redundancy circuit of a main memory, using bistable type non-volatile cells. Each cell includes floating-gate transistors, one of which is programmed to make the cell bistable. The floating-gate transistor is programmed by the application of a high voltage, to the gate, an intermediate voltage to the source and a zero voltage or a high impedance state to the drain.
