Abstract:
1. An electrically-programmable memory cell programmed by means of injection of channel hot electrons into a charge-storage element capacitively coupled to a memory cell channel for modulating a conductivity thereof depending on a stored amount of charge, comprising: a first and a second spaced-apart electrode regions formed in a semiconductor layer and defining a channel region there between, at least one of the first and second electrode regions acting as a programming electrode of the memory cell; a control electrode capacitively coupled to the charge-storage element, the charge-storage element being placed over the channel to substantially extend from the first to the second electrode regions, and being separated from the channel region by a dielectric layer, the dielectric layer having a reduced thickness in a portion thereof near the at least one programming electrode and over the channel region.
