Abstract
A high-voltage switching device for a flash memory includes at least one pumping transistor which includes one junction terminal and another junction terminal which are commonly connected to a control signal, and a gate terminal connected to a select signal. The high-voltage switching device also includes at least one switching transistor that includes one junction terminal connected to an input signal, another junction terminal connected to an output signal, and a gate terminal connected to the select signal. A layout of the high-voltage switching device includes a pumping active area in which the one junction terminal and the another junction terminal of the pumping transistor are disposed; a control interconnection area in which an interconnection of the control signal is wired; and a select interconnection area in which an interconnection of the select signal is wired.
