Abstract
A semiconductor memory has a serial access port transferring data consisting of a plurality of bits in a sequential manner. The serial access port includes a plurality of data registers provided correspondingly to a plurality of pairs of bit lines and divided into a plurality of groups, each of which is equal in number to the data to be transferred at one time each of a plurality of power control transistors supplies power to one of the data registers of one group and to one of the data registers of a different group. The data registers in one group are thus supplied with power from different power control transistors.
