From: NeoHebbian synapses to accelerate online training of neuromorphic hardware
1T-1H-1M unit cell implementation of the thermal neoHebbian synapse. During the dataframe presentation, the operation of the synapse is time multiplexed between a Spike integration - \(\phi _E\) = 0 and b e-update - \(\phi _E\) = 1 phase c Weight update is performed at the end of the dataframe - \(\phi _W\) = 1. The appropriate biasing conditions for each phase are shown in the schematic. F(.) & G(.) are defined in Eq. (2).
