Abstract
Phase shift circuitry is described herein. Phase shift circuitry can receive a column select signal from the processing unit (PU). The phase shift circuitry can phase shift the column select signal to generate additional column select signals. The phase shift circuitry can provide the column select signal and the additional column select signals to the array of memory cells to access a plurality of lookup tables representing activation functions used to implement a machine learning model.
