Abstract
In one aspect, a system for analog in-memory compute for a neural network includes an array of neurons. Each neuron of the array of neurons receives a pulse of magnitude xi, and duration t, wherein a product xi*yi provides a current proportional to the input for a time duration t, which is a charge associated with a particular neuron in response to the input being presented to that particular neuron. A reference cell includes a gate-drain connected flash cell configuration and coupled with the array of neurons. The reference cell is programmed to a pre-determined threshold voltage Vt-ref. The reference cell receives a pre-determined current, Iref, wherein, based on the Iref and a pre-determined threshold voltage Vt-ref, a voltage is created at a drain of the reference cell.
