Abstract:
Traditional neuromorphic chips generally use SRAM array to store the synaptic weights, which would lose data once power down. And the SRAM array can only be accessed through a single address decoding, which is not suitable for synaptic weights update. In this paper, a non-volatile synapse array and neuronal circuits based on 40 nm process combining with embedded phase change memory (ePCM) are proposed. This work would provide an effective, high-speed and low-power solution to store and update the neuron synaptic weights.
