Abstract: A data structure is maintained for performing a program operation that is allowed to be suspended to perform reads in a NAND device, where the data structure indicates a plurality of tiers, where each tier of the plurality of tiers has a number of allowed suspends of the program operation while executing in the tier, and where a sum of the number of allowed suspends for all tiers of the plurality of tiers equals a maximum allowed number of suspends of the program operation. In response to performing a resume of the program operation, after performing a read following a suspend of the program operation, a determination is made of a tier of the plurality of tiers for the program operation and a subsequent suspend of the program operation is performed only after a measure of progress of the program operation has been exceeded in the determined tier.

Abstract: Embodiments of the present disclosure may relate to a memory controller that may include a memory interface and a logic circuitry component coupled with the memory interface. In some embodiments, the logic circuitry component is to program one or more NAND cells of a multi-level NAND memory array via the memory interface with a first set of data in a first pass, determine a first temperature of the multi-level NAND memory array in association with the first pass, determine a second temperature of the multi-level NAND memory array, determine a temperature difference between the second temperature and the first temperature, and perform one or more operations based at least in part on a result of the determination of the temperature difference. Other embodiments may be described and/or claimed.
