Abstract
A system, comprising: a memory that stores computer-executable components; a processor, operably coupled to the memory, that executes the computer-executable components stored in the memory, wherein the computer-executable components comprise: an expression component that expresses the read current range in an RPU as read current Iwmin and Iwmax, a constant current source component that generates a reference current I, a computing component that subtracts the reference current value within from the read current value to generate an active net current read value that is negative, positive or null; a weighting component that analyzes the active current value and assigns it to a negative, positive or null weight.
