Abstract

PURPOSE:To obtain a semiconductor memory of CMOS dynamic ROM constitution that is easily be used, by installing a control circuit which produces the control signals to be supplied to an address decoder, a memory cell and a latching circuit respectively. CONSTITUTION:A control circuit 41 is installed to an ROM main body 11 to supply control signals phiA, phiB and phiC to a memory cell 13, a latching circuit 14 and an address decoder respectively. Like the decoder 12 and an output circuit 15, the circuit 41 is driven by an external signal such as a signal EC, etc. As a result, the special consideration to supply the control signal for driving the ROM from outside of an integrated circuit of the ROM is not required of the user.
