Abstract
A dummy cell includes two series-connected OFF-state transistors, one end of the series circuit which is formed by these two transistors is connected with a constant voltage source, and the other end of the series circuit is connected with a replica bit line. This suppresses a leak current flowing from the replica bit line to the dummy cell and therefore gives optimal start-up timing to a sense amplifier circuit.
