Disclosed herein is a device that includes: a set of address terminals supplied with a set of address signals, each of the address signals being changed in logic level; memory mats to which address ranges are allocated, respectively, the address ranges being different from each other, each of the memory mats including memory cells; and decoder units each provided correspondingly to corresponding memory mat. Each of the decoder units includes a set of first input nodes and a set of second input nodes, the set of first input nodes of each of the decoder units being coupled to the set of address terminals to receive the set of address signals, the set of second input nodes of each of the decoder units being coupled to receive an associated one of sets of control signals, each of the control signals being fixed in logic level.
