Abstract:
Various embodiments of a three-dimensional cross-point (3D X-point) memory cell design include one or more electrodes having an increased resistance compared to existing memory cell designs or compared to other electrodes within a same memory cell. A memory device includes an array of memory cells with each memory cell arranged between a word line and a bit line of the memory device. Some embodiments include additional material layers to increase memory cell resistance. Some embodiments include electrodes having an increased thickness to increase the resistance. Some embodiments include electrodes having a composition with a higher resistivity. Some embodiments include electrodes with increased interface resistance. Some embodiments include a combination of such features. In any case, the resulting increased memory cell resistance causes a reduction in the transient selection current for the given memory cell.
