Examples of the present disclosure provide apparatuses and methods related to performing a loop structure for operations performed in memory. An example apparatus might also include a controller configured to cause sensing circuitry to iterate through a plurality of first elements and a plurality of second elements via a loop structure to perform an operation using the plurality of first elements and the plurality of second elements, wherein a conditional statement associated with the loop structure is used to determine whether at least one of a plurality of bits stored as an iterator mask has a particular bit-value. An example apparatus might also include sensing circuitry controllable to perform a shift operation using the iterator mask at each iteration of the loop structure and perform an AND operation using the iterator mask at each iteration of the loop structure.
