High-bandwidth magnetoresistive random access memory devices
A magnetoresistive random access memory (MRAM) device includes a memory cell corresponding to one read bit line, one read word line, one write word line, and two or more write bit lines. The memory cell includes a first memory unit and a second memory unit each corresponding to a respective write bit line. Each of the first and second memory units comprises: a free magnetic region having a first easy axis, a pinned magnetic region having a second easy axis, and a tunneling barrier between the free magnetic region and the pinned magnetic region.
