Abstract:
Random access memory with CMOS-compatible nonvolatile storage element in series with storage capacitor is described herein. Embodiments may include memory devices and systems that have plurality of row lines, column lines, and memory cells each of which comprising an access transistor, a storage capacitor and a CMOS-compatible non-volatile storage element connected in series. The CMOS-compatible non-volatile storage element may store charges corresponding to a binary value. The node located between the CMOS-compatible non-volatile storage element and the storage capacitor may be defined as a storage node. During read operation, a cell may be selected, and the voltage at the storage node of the cell may be sensed at the corresponding column line, and the binary value may be determined based on at least the sensed voltage.
