Abstract:
A NOR flash memory device includes a multi level memory cell coupled to a bit line configured to be sensed in response to a word line voltage, and a discharge circuit configured to discharge the bit line when the multi level memory cell is sensed as an on cell.

Abstract:
A program operation for a NOR flash memory device is verified by programming data in a memory cell, performing a dummy verify operation on the memory cell, and performing a program verify operation on the memory cell based on a result of the dummy verify operation.
Abstract:
Provided is a method for analyzing a reflection wave using effective impedance. The method includes the steps of: a) modeling a reflection surface of a building two-dimensionally; and b) obtaining a reflection wave by radiating a radio wave to the modeled reflection surface and analyzing the obtained reflection wave through making medium uniform.
