The invention is to decrease leakage current which flows from high voltage terminal (Vpp) to earth terminal (Vss) in the sensing circuit of high voltage generator. The level sensor of the generator consists of transistors (M11,M12,M13), resistance (R2), nodes (N3,N4), and inverting gate (G2). If high voltage (Vpp) is higher than supplying voltage (Vcc) by an amount of threshold voltage, the transistor (M11) is turned on and the supply of current is started. Low sensing current flows from high voltage terminal (Vpp) to earth voltage terminal (Vss) and high drive current flows from high voltage terminal (Vpp) to supplying voltage terminal (Vcc) through resistance (R2). Therefore, power consumption is decreased.
