A semiconductor device may include at least one memory cell comprising a negative differential resistance (NDR) device and a control gate coupled thereto. The NDR device may include a superlattice including a plurality of stacked groups of layers, with each group of layers of the superlattice including a plurality of stacked base semiconductor monolayers defining a base semiconductor portion and at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions.
