Apparatuses and methods for in-memory operations

A system, comprising:

• a controller coupled to a memory device, wherein the memory device comprises:
• a first subset of a plurality of sub arrays of memory cells;
• a second subset of the plurality of subarrays of memory cells;
• sensing circuitry coupled to the first and second subsets, the sensing circuitry including a sense amplifier and a compute component coupled to a respective sense line of a plurality of sense lines for the first subset;
• and
• responsive to receipt from a host of instructions to perform a sequential plurality of operations, the controller is configured to direct:
• performance of the sequential plurality of operations in-memory on the number of data values in the sensing circuitry of the selected subarray in the first subset;
• and
• movement of a data value, resulting from the performance of the sequential plurality of operations, from the sensing circuitry to a selected destination;
• wherein the selected destination comprises selection from each of a selected row in a selected subarray of the first subset, a selected row in a selected subarray of the second subset, and a selected row in a selected vector register separate from the plurality of subarrays and coupled to the controller.

A method for operating a memory device, comprising:

• performing a sequential plurality of operations in-memory, by first sensing circuitry coupled to a selected first subarray in the memory device, on a plurality of data values subsequent to:
• sensing the plurality of data values in a selected second subarray in the memory device;
• and
• moving the plurality of sensed data values to the first sensing circuitry coupled to the selected first subarray;
• and
• storing results of each of the sequential plurality of operations by the selected first subarray until the performance of the sequential plurality of operations is completed to compute a result of a last of the sequential plurality of operations.
