VOLTAGE BOOSTING CIRCUIT AND BOOSTING METHOD AND MEMORY

摘要

PROBLEM TO BE SOLVED: To ensure a correct boosting operation with low power consumption even when an address is detected under asynchronous state by providing two precharge circuits, a capacitive element, etc. SOLUTION: A feeder line is connected with the gate of an insulated gate transistor and a power supply circuit of first voltage and it is precharged with a first voltage through the power supply circuit. A booster circuit comprises a booster precharge circuit 406 connected with the feeder line and precharging the feeder line with a first voltage, and a boosting capacitor 410 connected with the feeder line and boosting the precharge feeder line to a second voltage higher than the first voltage. A reset circuit resets the feeder line to first voltage upon finishing the operation of boosting circuit.
