Pseudo SRAM using resistive elements for non-volatile storage
Abstract:
A memory device includes a first select transistor having a first current electrode coupled to a first bit line, a control electrode and a second current electrode. A second select transistor has a first current electrode coupled to a second bit line, a control electrode and a second current electrode. A first bi-directional resistive element has a cathode coupled to the second current electrode of the first select transistor and an anode coupled to an internal node. A second bi-directional resistive element has a cathode coupled to the internal node and an anode coupled to the second current electrode of the second select transistor. A third transistor has a first current electrode coupled to a third bit line, a second current electrode coupled to the internal node, and a control electrode coupled to a word line.
