Abstract:
1. A multi-bit electro-mechanical memory device comprising: a substrate; a bit line on the substrate, the bit line extending in a first direction; a word line on the bit line, insulated from the bit line, and extending in a second direction transverse to the first direction; and a cantilever electrode including a shape memory alloy, the cantilever electrode having a first portion electrically directly connected to the bit line and a second portion extending in the first direction parallel with the bit line, and spaced apart from the word line by an air gap between a surface of the word line and the cantilever electrode, wherein the cantilever electrode, in a first state, is in electrical contact with the word line, and, in a second state, is spaced apart from the word line.
