Neural network with multiplexed snyaptic processing

摘要

In an apparatus for multiplexed operation of multi-cell neural network, the reference vector component values are stored as differential values in pairs of floating gate transistors. A long-tail pair differential transconductance multiplier is synthesized by selectively using the floating gate transistor pairs as the current source. Appropriate transistor pairs are multiplexed into the network for forming a differential output current representative of the product of the input vector component applied to the differential input and the stored reference vector component stored in the multiplexed transistor pair that is switched into the multiplier network to function as the differential current source. Pipelining and output multiplexing is also described in other preferred embodiments for increasing the effective output bandwidth of the network.
