Document Type and Number:
WIPO Patent Application WO/2021/066100
Kind Code:
A1
Abstract:
Provided is a driving method of a simplified synapse circuit. When a first pre-spike pulse precedes a first post-spike pulse, a second pre-spike pulse from an input circuit 20a is used as a time window in which writing of a connection weight is permitted, and the first post-spike pulse from a neuron circuit 17 is used as a writing pulse of a writing timing control for the connection weight. When the first post-spike pulse precedes the first pre-spike pulse, a second post-spike pulse from the neuron circuit 17 is used as a time window, and the first pre-spike pulse from the input circuit 20a is used as a writing pulse. The second pre-spike pulse and the second post-spike pulse are respectively synchronized with the first pre-spike pulse and the first post-spike pulse to be output.
