Abstract: Provided are a flash memory device and a method of verifying the same. The flash memory device includes: a memory cell for storing data; a sense amplifier for reading information of the memory cell; a load current input device for providing a load current to the sense amplifier; and a control circuit for controlling the load current input device to provide a load current during a memory cell reading operation, verifying the memory cell by using a program verify voltage if the memory cell is a programmed memory cell, and verifying the memory cell by using a compensated erase verify voltage if the memory cell is an erased memory cell.
