ABSTRACT:
The present invention disclosed a method of reading a flash memory cell and a read voltage generating circuit which can perform a stable read operation regardless of a power supply voltage by applying a voltage of 2V to the source, a voltage of 0V to the drain, a power supply voltage Vcc to the select gate, and a clamping voltage output from the read voltage generating circuit to the control gate upon a read operation of a split gate flash memory cell.
