Patent ID: 8735862

Claim:
A memory cell, comprising: a bottom electrode having an upper surface with an upper surface area; first and second programmable material plates having length, width and thickness dimensions; the thickness dimensions being less than the length and width dimensions; the programmable material plates having thin edges along the thickness dimensions; the first programmable material plate being supported edgewise over the bottom electrode; the first programmable material plate having a bottom thin edge and an upper thin edge; only the bottom thin edge of the first programmable material plate being against the bottom electrode, and being directly against only a portion of the upper surface area of the bottom electrode; the second programmable material plate being supported edgewise over the first programmable material plate; the second programmable material plate having a bottom thin edge and a top thin edge; the bottom thin edge of the second programmable material plate being directly against the top thin edge of the first programmable material plate; and a top electrode over the top thin edge of the second programmable material plate.
