ABSTRACT:
A dynamic type semiconductor memory device includes a memory cell having a capacitor for storing an amount of charge corresponding to data and, an n-channel MOS transistor to control charging and discharging to and from the capacitor, and a control unit to permit a read/write operation of the memory cell. The control unit of the memory device includes a drive circuit for generating turn on and turn off voltages, a charge pump circuit connected to the gate of the memory cell, and a switching element connected between the drive circuit and the gate of the MOS transistor.
