    Abstract: A system includes a memory device and a processing device, operatively coupled with the memory device, to perform operations including: receiving a request to perform a read operation on a segment of the memory device; determining whether a temperature offset value of the segment satisfies a threshold criterion associated with a program erase cycle count of the segment; and responsive to determining that the temperature offset value satisfies the threshold criterion, performing a corrective read operation on the segment of the memory device, wherein a sense time parameter of the corrective read operation is modified according to the temperature offset value and the program erase cycle count.

    Abstract: The disclosure configures a memory sub-system controller to use prior read verify operations to selectively apply enhancements to read window budgets (RWB). The controller receives a request to perform a memory operation on data stored in an individual memory component of a set of memory components. The controller accesses RWB tracking information associated with the individual memory component and determines that the tracking information associated with the individual memory component indicates a need for enhancing a RWB associated with the memory operation. The controller applies one or more enhancement processes to the individual memory component in response to determining that the tracking information associated with the individual memory component indicates the need for enhancing the RWB associated with the memory operation.

    Abstract: Systems, methods, and apparatus related to memory devices. In one approach, a cross-point memory array includes memory cells. A media controller reads one or more first memory cells and determines a read status. The read status indicates an error when reading the first memory cells. In response to this error, the controller refreshes the first memory cells. The controller uses the read status to determine zero-to-one failures associated with the first memory cells. If a number of these failures exceeds a threshold, then a refresh is applied to neighboring memory cells of the first memory cells. The physical addresses for the neighboring memory cells are determined by the controller from the physical addresses for the first memory cells.

    Abstract: A system includes a memory device and a processing device, operatively coupled with the memory device, to perform operations including: receiving a request to perform a memory access operation on a set of cells associated with a wordline of the memory device; determining that the wordline is disposed on a first deck of the memory deck; responsive to determining that the wordline is disposed on the first deck, determining that the wordline is associated with a first group of wordlines associated with the first deck; and responsive to determining that the wordline is associated with the first group of wordlines associated with the first deck, performing the memory access operation on the set of cells connected to the wordline using a first time sense parameter, wherein the first time sense parameter corresponds to the first group of wordlines associated with the first deck.
