Phase-change random access memory device and method of operating the same

摘要

A phase-change random access memory device may include a phase-change pattern, a first electrode structure connected to the phase-change pattern, and a second electrode structure spaced apart from the first electrode structure and connected to the phase-change pattern, wherein at least one of the first electrode structure and the second electrode structure includes a plurality of resistor patterns connected to the phase-change pattern in parallel.
