Memory calibration device, system and method

A method for memory array calibration, the method comprising:

• applying, using calibration circuitry, a pattern of test data to a memory array having a plurality of memory cells, the memory array including a plurality of in-memory compute clusters;
• generating, using the calibration circuitry, calibration information based on the applying of the pattern of test data, wherein generating the calibration information includes analyzing output provided by a sensing circuit coupled to the plurality of memory cells in response to the applying of the pattern of test data;
• storing, using the calibration circuitry, the generated calibration information in a distributed manner within at least some memory cells of the plurality of memory cells;
• and
• after the storing of the generated calibration information in the distributed manner and as part of one or more in-memory compute operations on multiple data values stored in the plurality of memory cells, combining at least a portion of the generated calibration information with the multiple data values, wherein the multiple data values are stored in an in-memory compute cluster of the memory array.
