ABSTRACT:
A non-volatile memory cell includes an upper electrode; a lower electrode and a state-variable region, in which a conductive state changes only once. The state variable region is formed in a region between the upper electrode and the lower electrode. The state-variable region comprises a first semiconductor layer of a first conductive type; and second semiconductor layers of a second conductive type, opposing to the first conductive type, which are formed on upper and lower surfaces of the first semiconductor layer via PN junctions.
