Abstract
In some examples, a method may be performed by a multiply-accumulate circuit. As part of the method a row driver of the multiply-accumulate circuit may drive a row value line based on an input vector bit of an input vector received by the row driver. The row driver may also drive a row line that controls a corresponding memristor according to the input vector bit. The corresponding memristor may store a weight value bit of a weight value to apply to the input vector for a multiply-accumulate operation. The method may further include a sense amplifier generating an output voltage based on a current output from the corresponding memristor and counter circuitry adjusting a counter value that represents a running total of the multiply-accumulate operation based on the row value line, the output voltage generated by the sense amplifier, or a combination of both.
