Abstract

A method for measuring interference in a memory device is provided. The method includes: programming a selected memory cell among a plurality of memory cells connected in series between a bit line and a source line; measuring a first noise value of the programmed selected memory cell; programming an adjacent memory cell adjacent to the selected memory cell among the plurality of memory cells; measuring a second noise value of the selected memory cell, after the programming of the adjacent memory cell is completed; and determining interference on the selected memory cell based on the first noise value and the second noise value. The first noise value and the second noise value are measured by detecting a low frequency noise of a cell current of the selected memory cell.
