US Patent 7952912 Static random access memory cell and devices using same

A bit-cell may include a pair of cross-coupled inverters, a left bit-line, a right bit-line, a word-line and a write-line. The left bit-line may be coupled to a left inverter of the cross-coupled inverters via a left word-line transistor and a left write-line transistor. The right bit-line may be coupled to a right inverter of the cross-coupled inverters via a right word-line transistor and a right write-line transistor. The word-line may be coupled to the gates of the left and right word-line transistors and the write-line may be coupled to the gates of the left and right write-line transistors. A memory device may include a controller, an array of such bit-cells and a differential sensing buffers. Further, a computing device may include a processor and a memory device having the above bit-cells.
