摘要:
Disclosed herein are related to a memory cell including magnetic tunneling junction (MTJ) devices. In one aspect, the memory cell includes a first layer including a first transistor and a second transistor. In one aspect, the first transistor and the second transistor are connected to each other in a cross-coupled configuration. A first drain structure of the first transistor may be electrically coupled to a first gate structure of the second transistor, and a second drain structure of the second transistor may be electrically coupled to a second gate structure of the first transistor. In one aspect, the memory cell includes a second layer including a first MTJ device electrically coupled to the first drain structure of the first transistor and a second MTJ device electrically coupled to the second drain structure of the second transistor. In one aspect, the second layer is above the first layer.
