Nonvolatile memory cell and nonvolatile memory device comprising the same
Abstract:
A nonvolatile memory cell resistance change type nonvolatile memory cell configured to store information by changing an electrical resistance according to application of electrical stress is provided and a nonvolatile memory device including the nonvolatile memory cell is provided. The resistance change type nonvolatile memory cell includes a resistance change material layer including a resistance change material; a ferroelectric layer on a first side of the resistance change material layer, the ferroelectric layer configured to change an electrical resistance of the resistance change material layer according to a polarization direction and polarization size of a ferroelectric therein; a first electrode on the ferroelectric layer and configured to control the polarization direction and the polarization size of the ferroelectric based on an applied voltage; and a second electrode and a third electrode on the resistance change material layer with the first electrode therebetween.
