Abstract: Methods and apparatus related to a mechanism for quickly adapting garbage collection resource allocation for an incoming I/O (Input/Output) workload are described. In one embodiment, non-volatile memory stores data corresponding to a first workload and a second workload. Allocation of one or more resources in the non-volatile memory is determined based at least in part on a determination of an average validity of one or more blocks, where the one or more candidate bands are to be processed during operation of the first workload or the second workload. Other embodiments are also disclosed and claimed.

Abstract: A refreshing method is described. The method includes recognizing a set of blocks of a non-volatile memory for refreshing and then refreshing a subset of the data within the blocks, where, invalid data within the blocks is not recognized for refreshing and a group of blocks whose oldest data has not aged for a pre-set time period is not recognized for refreshing.

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.
