Abstract

This paper proposes a 3-D floating-gate (FG) synapse array for neuromorphic applications. The designed device has certain advantages over previous planar FG synapse devices: a smaller cell size due to the stacked structure and smaller operation voltage by the gate-allaround geometry. In addition, the operation method to implement spike time-dependent plasticity is proposed and demonstrated. The proposed array based on commercialized flash memory technology is expected be one of the most promising candidate architecture for neuromorphic applications.
