    Abstract: A hardware cell and method for performing a digital XNOR of an input signal and weights are described. The hardware cell includes input lines, a plurality of pairs of magnetic junctions, output transistors and at least one selection transistor coupled with the output transistors. The input lines receive the input signal and its complement. The magnetic junctions store the weight. Each magnetic junction includes a reference layer, a free layer and a nonmagnetic spacer layer between the reference layer and the free layer. The free layer has stable magnetic states and is programmable using spin-transfer torque and/or spin-orbit interaction torque. The first magnetic junction of a pair receives the input signal. The second magnetic junction of the pair receives the input signal complement. The output transistors are coupled with the magnetic junctions such that each pair of magnetic junctions forms a voltage divider. The output transistors form a sense amplifier.

    Abstract: Exemplary embodiments provide for fabricating a nanosheet stack structure having one or more sub-stacks. Aspects of the exemplary embodiments include: growing an epitaxial crystalline initial stack of one or more sub-stacks, each of the sub-stacks having at least three layers, a sacrificial layer A, and at least two different non-sacrificial layers B and C having different material properties, wherein the non-sacrificial layers B and C layers are kept below a thermodynamic or kinetic critical thickness corresponding to metastability during all processing, and wherein the sacrificial layer An is placed only at a top or a bottom of each of the sub-stacks, and each of the sub-stacks is connected to an adjacent sub-stack at the top or the bottom using one of the sacrificial layers A; proceeding with fabrication flow of nanosheet devices, such that pillar structures are formed at each end of the epitaxial crystalline stack that to hold the nanosheets in place after selective etch of the sacrificial layers; and selectively removing sacrificial layers A to all non-sacrificial layers B and C, while the remaining layers in the stack are held in place by the pillar structures so that after removal of the sacrificial layers An, each of the sub-stacks contains the non-sacrificial layers B and C.
