Semiconductor memory device having register groups for writing and reading data
 A semiconductor memory device comprises an array of memory cell units, each of which has a plurality of MOS transistors connected in series and a plurality of information storage capacitors corresponding in number to the MOS transistors and each having its one end connected to the source of a corresponding one of the MOS transistors, and a plurality of register groups each of which is adapted to temporarily store information stored in one of the memory cell units for each column of the array in order to read from and write into each memory cell unit.
