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 comprising a primary latch coupled to a sense line of the array. The sensing circuitry can be configured to perform a first operation phase of a logical operation by sensing a memory cell coupled to the sense line, perform a number of intermediate operation phases of the logical operation by sensing a respective number of different memory cells coupled to the sense line, and accumulate a result of the first operation phase and the number of intermediate operation phases in a secondary latch coupled to the primary latch without performing a sense line address access.

The present disclosure includes apparatuses and methods related to performing compare and/or report operations using sensing circuitry. An example method can include charging an input/output (IO) line of a memory array to a voltage. The method can include determining whether data stored in the memory array matches a compare value. The determination of whether data stored matches a compare value can include activating a number of access lines of the memory array. The determination can include sensing a number of memory cells coupled to the number of access lines. The determination can include sensing whether the voltage of the IO line changes in response to activation of selected decode lines corresponding to the number of memory cells.

Examples of the present disclosure provide apparatuses and methods for performing division operations in a memory. An example apparatus comprises a first address space comprising a first number of memory cells coupled to a sense line and to a first number of select lines wherein the first address space stores a dividend value. A second address space comprises a second number of memory cells coupled to the sense line and to a second number of select lines wherein the second address space stores a divisor value. A third address space comprises a third number of memory cells coupled to the sense line and to a third number of select lines wherein the third address space stores a remainder value. Sensing circuitry can be configured to receive the dividend value and the divisor value, divide the dividend value by the divisor value, and store a remainder result in the third number of memory cells.

Examples of the present disclosure provide devices and methods for accessing a memory array address space. An example memory array comprising a first address space comprising memory cells coupled to a first number of select lines and to a number of sense lines and a second address space comprising memory cells coupled to a second number of select lines and to the number of sense lines. The first address space is independently addressable relative to the second address space.

The present disclosure includes apparatuses and methods related to identifying an extremum value using sensing circuitry. An example method can include determining a location of an extremum value of a set of N data values stored as vectors in a memory array. A number of operations to determine the location of the extremum value can remain constant with respect to a value of N. The method can include determining the value of the extremum by reading memory cells coupled to the sense line based on the determined location of the extremum value.
