Phase-change memory device having phase change material pattern shared between adjacent cells and electronic product including the phase-change memory

摘要

Provided is a phase-change memory device including a phase-change material pattern of which strips are shared by neighboring cells. The phase-change memory device includes a plurality of bottom electrodes arranged in a matrix array. The phase-change material pattern is formed on the bottom electrodes, and the strips of the phase-change material pattern are electrically connected to the bottom electrodes. Each strip of the phase-change material pattern is connected to at least two diagonally neighboring bottom electrodes of the bottom electrodes.
