a Schematic of biological synapse. Signal transmission from the pre-synaptic terminal to the post-synaptic terminal is realized through ion channel by releasing neurotransmitters. b The synaptic weight PSC of a flexible SFeM versus gate pulse numbers, indicating the long-term potentiation and depression characteristics. c Cumulative probability of a flexible SFeM with respect to 32 independent drain-to-source conductance states. The conductance is programmed by applying different numbers of gate voltage pulses with 5 V amplitude and 10 ms width. d Structure of the five-layer CNN used for MNIST image recognition containing two convolutional layers (C1 and C2), two maximum-pooling layers (P1 and P2), and a fully-connected layer. The input is a 28 × 28 grayscale (8 bit) digit image. Bottom labels provide the feature map dimension (height × width × channel depth) or the vector dimension.
