Abstract
A random access memory includes a redundancy repair circuit having a plurality of parallel connected transistors and a plurality of fuses connected to respective drains of the plurality of transistors. An electrically resistive element is connected to a common node to reduce a difference in operating speeds between a first case in which the circuit is precharged from a state in which discharge to a low level was effected via one of the transistors and a case in which precharging of the circuit is effected from a state in which discharging was carried out via a plurality of the transistors.
