Abstract
Provided is a simplified driving method of a synapse circuit. In a case where a first pre-spike pulse precedes a first post-spike pulse, a second pre-spike pulse from an input circuit is used as a time window that allows writing of a coupling weight, and the first post-spike pulse from a neuron circuit is used as a write pulse for controlling a write timing of the coupling weight. In a case where the first post-spike pulse precedes the first pre-spike pulse, a second post-spike pulse from the neuron circuit is used as the time window, and the first pre-spike pulse from the input circuit is used as the write pulse. The second pre-spike pulse and the second post-spike pulse are output in synchronization with the first pre-spike pulse and the first post-spike pulse, respectively.
