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.

Abstract: Disclosed are a method of forming a contact structure, a method of fabricating a semiconductor device, a contact structure, and a semiconductor device including the same. A method of forming a contact structure may comprise forming a porous silicon layer on a substrate by using an epitaxy process, forming a dielectric layer on the porous silicon layer, forming a metal layer on the dielectric layer, forming a silicide member having a three-dimensional structure in the porous silicon layer by diffusing metal atoms of the metal layer into the porous silicon layer through the dielectric layer and reacting the diffused metal atoms with the porous silicon layer in a heat treatment process, removing the metal layer and the dielectric layer, and forming a conductive layer in contact with the silicide member.
