Abstract

A memory device includes at least one memory cell having a first transistor coupled between a first storage node and a first supply voltage; a second transistor coupled between a second storage node and the first supply voltage and a single resistance switching element. Control terminals of the first and second transistors are coupled to the second and first storage nodes respectively. The single resistive switching element is coupled in series with the first transistor and is programmable to have one of first and second resistances. The first storage node is coupled to a first access line via a third transistor connected to said first storage node, and the second storage node is coupled to a second access line via a fourth transistor connected to the second storage node.
