Abstract
A semiconductor memory is provided with a first memory cell group, a second memory cell group, a first register for a serial output operation for holding information related to the first memory cell group, a second register for a serial output operation for holding information related to the second memory cell group, and transfer means for transferring information related to either the first or second memory cell group to either the first or second serial output register. By virtue of this arrangement, while the information transferred to the first serial output register is being serially output therefrom, information can simultaneously be transferred to the second serial output register by the transfer means.
