Abstract
Disclosed is a synaptic element that uses electro-migration in an interconnect structure, wherein the interconnect structure is optimized to give control of resistivity change following current flow. The synaptic element exhibits resistivity that is a function of the amount (of charge) and direction of current flow, wherein a continuously variable resistance is obtained by controlling the volume of a designed void in the interconnect structure.
