A memory cell is provided for use in a multi-port RAM. In addition to a flip-flop circuit for memorizing data and a transfer gate for transmitting data into the flip-flop, at least a transistor series having a first, a second, and a third field effect transistors are provided. These transistors are series connected between a bit line of said RAM and a low electric supply so as to read out data from said flip-flop circuit within a short period.
