Abstract
A clock generator circuit of a dynamic random access memory (RAM) comprises a power-on reset circuit and an NOR gate conneced to a row address strobe (RAS) terminal and the reset circuit. In operation, the power-on reset circuit generates a one-shot pulse immediately after the power supply is turned on. During a period of a pulse width of the one-shot pulse, this clock generator circuit operates as if it receives a high-level row address strobe (RAS) signal and, as a result, it is possible to reduce an excessive current flowing into the dynamic random access memory (RAM) at the time of turning on the power supply.
