Input circuitry for analog neural memory in a deep learning artificial neural network

Abstract

Numerous embodiments of input circuitry for an analog neural memory in a deep learning artificial neural network are disclosed. In one example, an input block for providing an input to a vector-by-matrix multiplication array in a neural memory system, the vector-by-matrix multiplication array comprising non-volatile memory cells arranged in rows and columns, comprises a digital-to-analog converter; a voltage-to-current converter to generate a current responsive to an output of the digital-to-analog converter; and a current to voltage logarithmic converter for generating a voltage that is a function of a logarithm of the current.

Dependencies are inferred from the claim text.
