ADAPTIVE AND/OR ITERATIVE OPERATIONS IN EXECUTING A READ COMMAND TO RETRIEVE DATA FROM MEMORY CELLS

Abstract:

A memory sub-system configured to adaptively and/or iteratively determine sub-operations of executing a read command to retrieve data from memory cells. For example, after receiving the read command from a processing device of a memory sub-system, a memory device starts an atomic operation of executing the read command in the memory device. The memory device can have one or more groups of memory cells formed on an integrated circuit die and a calibration circuit configured to measure signal and noise characteristics of memory cells in the memory device. During the atomic operation, the calibration circuit generates outputs, based on which a read manager of the memory sub-system identifies sub-operations to be performed in the atomic operation and/or decides to end the atomic operation.
