Abstract:
1. A flash memory device, comprising: a memory cell array having a plurality of memory cells therein; a program controller for controlling the programming of the memory cells; a high voltage generating portion for generating a pass voltage and a program voltage by the control of the program controller; and a wordline driver for outputting either the pass voltage or the program voltage to the corresponding wordline of the memory cell array by the control of the program controller; wherein the wordline driver comprises: a first switch for outputting the pass voltage in response to a pass voltage activation signal input from the program controller; a second switch for outputting the program voltage to the wordlines in response to a program voltage activation signal input from the program controller; and a voltage compensating portion for controlling the output of the program voltage such that the level of the program voltage is always higher than the level of the pass voltage.
