Abstract

See full text

A system and method for fabricating a memory array device. An example memory array device includes a plurality of memory cells, each including a FET over a substrate and a memory element over the FET. Each memory element includes a plurality of epitaxially grown memory element layers. The memory elements formed utilizing two etches through all epitaxially grown layers. Each of these etches can be split to two separate processes specific to CMOS transistor etch and to memory element etch. The memory array device includes a plurality of gate conductors configured along a first axis, in parallel. Each FET of the memory cells adjacent to two gate conductors. The memory array device includes a plurality of bit lines configured along a second axis, in parallel, and electrically coupled to a plurality of memory elements along the second axis.
