Abstract
An in-memory computation device performs a multiply-and-accumulate (MAC) operation. A computation array includes groups of memory cells coupled to a bitline, each group storing a computational weight and having a positive cell flowing a positive-cell current and a negative cell flowing a negative-cell current which are a function of a total current and the sign and absolute value of the respective computational weight. A row-activation circuit receives an input signal and provides, for each input value, during an elaboration interval, a positive-activation signal having a positive-activation duration and a negative-activation signal having a negative-activation duration, the durations being a function of an elaboration duration and of the sign and absolute value of the respective input value. A column-elaboration circuit samples bitline current and provides, in response thereto, at least one output signal.
