Abstract

See full text

A method can include, for each row of a nonvolatile memory (NVM) cell array, generating a multiply-accumulate (MAC) result for the row by applying input values on bit lines. Each MAC result comprising a summation of an analog current or voltage that is a function of each input value modified by a corresponding weight value stored by the NVM cells of the row. By operation of at least one multiplexer, one of the rows can be connected to an analog-to-digital converter (ADC) circuit to convert the analog current or voltage of the row into a digital MAC value. A storage element of each NVM cell can be configured to store a weight value that can vary between no less than three different values. Corresponding devices and systems are also disclosed.
