Abstract
Apparatuses and methods determine a length of a longest element in a memory. An example method comprises determining, using a controller to control sensing circuitry, a length of a longest element of a plurality of variable length elements of a vector stored in a memory array.
Claims20
A method, comprising:
- determining, using sensing circuitry coupled to a memory array and controlled by a controller, a length of a longest element of a plurality of variable length elements of a vector stored in the memory array by:
- performing, in the sensing circuitry, a shift operation on an element mask vector indicating most significant bits of the plurality of variable length elements of the vector.
An apparatus comprising:
- a group of memory cells, coupled to an access line of a memory array and a plurality sense lines, and configured to store a plurality of variable length elements;
- and
- a controller configured to cause sensing circuitry coupled to the plurality of sense lines to:
- perform, in the sensing circuitry, a shift operation on a bit vector indicating most significant bits of the plurality of variable length elements of the vector to determine a length of the longest element;
- and
- concurrently performing an operation with a determination of the length of the longest element, wherein the operation is performed using at least one of the plurality of variable length elements.

A method, comprising:
- receiving, from a host, an element mask vector indicating a most significant bit for each element of a plurality of variable length elements;
- determining, using a controller to control sensing circuitry, a length of a longest element of the plurality of variable length elements of a vector by:
- performing, in the sensing circuitry, a shift operation on the element mask vector to determine the length of the longest element of the plurality of variable length elements;
- and
- providing the length of the longest element to the host.
