STATIC RAM:

Flip-Flops are the basic memory cells in a static RAM. Each flip-flop is based on either two bipolar transistors or two Metal Oxide Semiconductors Field-Effect Transistors (MOSFETS). As many of these memory cells are needed as there are bits to be stored. Thus, in a 16K-bit static memory there are 16384 flip-flops, i.e. 32768 transistors. All these transistors are accommodated on a single silicon chip approximately 4mm². Figure shows a basic memory cell in a static RAM
