POWER ON RESET CIRCUIT OF SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: A power on reset circuit of semiconductor memory device is provided to prevent generation of static current. CONSTITUTION: A power on reset circuit of semiconductor memory device comprises a pulse generating part(111), a charge discharging part(113) and a static current removing part(115). The pulse generating part(111) senses source voltage and generates a pulse at the beginning of appliance of the source voltage. The charge discharging part(113) discharges every charge remained at the pulse generating part(111) when the source voltage is off. The static current removing part(115) removes the static current generated at the pulse generating part(111).
