Abstract

Embodiments disclosed include memory cell operating methods, memory cell programming methods, memory cell reading methods, memory cells, and memory devices. In one embodiment, a memory cell includes a wordline, a first bitline, a second bitline, and a memory element. The memory element is electrically connected to the wordline and selectively electrically connected to the first bitline and the second bitline. The memory element stores information via a resistive state of the memory element. The memory cell is configured to convey the resistive state of the memory element via either a first current flowing from the first bitline through the memory element to the wordline or a second current flowing from the wordline through the memory element to the second bitline.
