A selector is a device used in each bit cell in a memory array to ensure optimized cell access within the array, while suppressing unwanted current flow in unselected cells (called “sneak path” current). The type of selector used has a significant impact on the area of a memory bit cell. In the embedded space, a transistor is typically used as the selector device, but density requirements in discrete chips dictate the need to use other selector devices such as an OTS selector.
