Systems and methods for analog vector by matrix multiplier

Abstract

A system may include a memory array for VMM and includes a matrix of devices. The devices may be configured to receive a programming signal to program a weight to store a matrix of weights. The devices may be configured to receive a digital signal representative of a vector of input bits. The devices may generate an analog output signal by individually multiplying input bits by a corresponding weight. The system may include multiple ADCs electrically coupled to a corresponding device. Each ADC may be configured to convert a corresponding analog output signal to a digital signal based on a current level of the corresponding analog output signal. The system may include registers electrically coupled to a corresponding ADC configured to shift and store an output vector of bits of a corresponding digital output signal based on an order of the vector of input bits received by the corresponding device.
