- Abstract
- In this paper, an interfacial phase change memory (iPCM) based on superlattice (SL) structure was fabricated by stacking GeTe/Sb2Te3 alternatively, and synaptic characteristics such as linearity and symmetry of long-Term potentiation (LTP)/long-Term depression (LTD) were measured by Keithley 4200A-CSC parameter analyzer. The conventional phase change memory (PCM) based on Ge-Sb-Te alloy with the identical bottom electrode contact size was also fabricated for comparison.
