Abstract

A neural network computing engine having an array of charge-trap-transistor (CTT) elements which are utilized as analog multipliers with all weight values preprogrammed into each CTT element as a CTT threshold voltage, with multiplicator values received from the neural network inference mode. The CTT elements perform computations of a fully connected (FC) neural network with each CTT element representing a neuron. Row resistors for each row of CTT element sum output currents as partial summation results. Counted pulse generators write weight values under control of a pulse generator controller. A sequential analog fabric (SAF) feeds multiple drain voltages in parallel to the CTT array to enable parallel analog computations of neurons. Partial summation results are read by an analog-to-digital converter (ADC).
