ABSTRACT:
A flash memory includes a plurality of MOSFETs. Each of the MOSFETs comprises a first conductive type substrate, a source, and a drain. The source and the drain are formed on one major surface of the substrate. A floating gate is situated over the major surface via a first insulation layer in a manner to control a current flowing through a channel between the source and the drain. The floating gate is highly resistive so as to essentially hold electrons in the region into which they were are injected from a depletion layer formed in the channel. A control gate is further provided over the floating gate via a second insulation layer.
