Abstract

A dynamic memory cell uses a low barrier Schottky contact at a drain region to eliminate the need for an external gating diode. The drain is separated from source and injector regions by a heavily doped N+ reach through region extending to a heavily doped N+ blanket semiconductor. Holes injected into one of the separated regions are trapped by high-low junctions and are detected by sensing the source-drain current.
