Abstract
In a static memory, a memory cell is constituted by only the same-channel MOSFETs. With the MOSFETs of the same channel, no well isolation region is required, and a cell size can be decreased. Moreover, the high potential side power source of a flip-flop can be used as a read word line. Thus the read word line can be driven by an ECL logic circuit.
