ALEXANDRIA, Va., April 21 -- United States Patent no. 12,608,599, issued on April 21, was assigned to Tohoku University (Miyagi, Japan).
"Driving method of synapse circuit" was invented by Yitao Ma (Miyagi, Japan) and Tetsuo Endoh (Miyagi, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "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 pul...
