US Patent 10395710 Magnetic memory emulating dynamic random access memory (DRAM)

The present invention is directed to a magnetic memory device comprising a memory array structure that includes a first memory array comprising a first plurality of memory cells and a second memory array comprising a second plurality of memory cells. Each memory cell of the first and second plurality of magnetic memory cells includes a magnetic memory element and a two-terminal selector coupled in series. The memory array structure further includes a first multiplexer coupled to a third plurality of first conductive lines with each line connected to a respective column of the first plurality of memory cells; a second multiplexer coupled to a fourth plurality of first conductive lines with each line connected to a respective column of the second plurality of memory cells; a sense amplifier, whose input is connected to the output of the first multiplexer and the output of the second multiplexer; and one or more latches coupled to the sense amplifier.
