Abstract

A non-volatile dynamic RAM circuit where each memory cell includes an access transistor, a floating gate structure, and a recall transistor connected in series between an I/O bit line and a common line. A conducting plate and storage node of the floating gate structure functions as the volatile storage element of the cell and the floating gate functions as the non-volatile storage element.
