Abstract
The present disclosure includes apparatuses and methods related to performing logical operations using sensing circuitry. An example apparatus comprises an array of memory cells and sensing circuitry coupled to the array. The sensing circuitry can include a sense amplifier coupled to a pair of complementary sense lines and a compute component coupled to the sense amplifier via pass gates coupled to logical operation selection logic. The logical operation selection logic can be configured to control pass gates based on a selected logical operation.
