Abstract

Examples of the present disclosure provide apparatuses and methods related to performing comparison operations in a memory. An example apparatus might include a first group of memory cells coupled to a first access line and configured to store a first element. An example apparatus might also include a second group of memory cells coupled to a second access line and configured to store a second element. An example apparatus might also include sensing circuitry configured to compare the first element with the second element by performing a number of AND operations, OR operations, SHIFT operations, and INVERT operations without transferring data via an input/output (I/O) line.
