发明名称 High voltage switch circuit having boosting circuit and flash memory device including the same
摘要 A high-voltage switch circuit includes an enable control circuit, a feedback circuit, a boosting circuit, and a high voltage switch. The enable control circuit precharges an output node to a set voltage in response to an enable signal. The feedback circuit supplies a feedback voltage to an input node in response to a switch control voltage generated from the output node when the output node is precharged. The boosting circuit boosts the feedback voltage and outputs a boosting voltage to the output node, in response to clock signals, thereby increasing the switch control voltage. The high voltage switch is turned on or off in response to the switch control voltage, and is turned on to receive a high voltage and output the received high voltage. The boosting circuit includes an amplification circuit of a cross-coupled type.
