A semiconductor integrated circuit has K (K is a natural number of 2 or more) number of memory cells coupled to a same word line, and multiple sense amplifier circuits coupled to the memory cells. The multiple sense amplifier circuits are divided into N (N is a natural number of 2 or more) number of groups. Among the N number of groups, after a first group of sense amplifier circuits is activated and carrying out a predetermined read-out operation, a second group of the sense amplifier circuits is activated and the predetermined read-out operation is carried out, and an Nth group of the sense amplifier circuits is activated sequentially to carry out the predetermined read-out operation.
