Flexible Low-Power Superlattice-Like Phase Change Memory

Abstract

Flexible electronics involving applications in wearable health monitoring systems such as electronic skin [1] and Internet-of-Things (e.g. environmental or food monitoring) require integrated memory and low power consumption [2] , [3] . Although phase-change memory (PCM) has already been adopted in commercial products and its process temperature (<200°C) is compatible with flexible substrates like polyimide (PI) [4] , integration concerns remain over its relatively high reset current ( I reset ) and power ( P reset ) [5] , including on flexible substrates [6] .
