Abstract:
A solid-state memory in which write assist circuitry is implemented within each memory cell. Each memory cell includes a storage element, such as a pair of cross-coupled inverters, and an equalization gate connected between the storage nodes of the storage element. The equalization gate may be realized by two transistors in series, or as a double-gate transistor. The equalization gate is controlled by a word line indicating selection of the row containing the cell in combination with a column select signal indicating selection of the column containing the cell in a write cycle. Upon a write to a selected cell, both gates are turned on, connecting the storage nodes of the cell to one another and assisting the write of the opposite date state from that previously stored.
