Abstract
Disclosed are a semiconductor memory device and a method of manufacturing the same. A first conductive line extends in a first direction on a substrate and has a plurality of protrusions and recesses that are alternately formed thereon. A second conductive line is arranged over the first conductive line in a second direction such that the first and the second conductive lines cross at the protrusions. A plurality of memory cell structures is positioned on the protrusions of the first conductive line and is contact with the second conductive line. A thermal insulating plug is positioned on the recesses of the first conductive line and reduces heat transfer between a pair of the neighboring cell structures in the first direction. Accordingly, the heat cross talk is reduced between the neighboring cell structures along the conductive line.
