PROBLEM TO BE SOLVED: To provide a semiconductor memory device that keeps a total peak bandwidth constant even when the transfer amount of data accessed at a time in an identical chip is changed.SOLUTION: A semiconductor memory device includes: a plurality of banks; a plurality of data input/output terminals; a plurality of control signal terminals; a plurality of address signal terminals; and at least one or a plurality of virtual chips which can operate as one independent chip by integrating the banks. Each of the plurality of data input/output terminals belongs to any one of the one or plurality of virtual chips; and the plurality of control signal terminals and the plurality of address signal terminals are shared by each of the one or plurality of virtual chips. |
