Abstract: A processing device in a memory sub-system receives a request to execute a garbage collection operation associated with a first memory die of a set of memory dies of a memory sub-system. A determination is made that the first memory die is associated with a slow programming time category of a set of programming time categories, where the set of programming time categories includes the slow programming time category and a fast programming time category. A second memory die of the set of memory dies is identified, where the second memory die is associated with the fast programming time category. The garbage collection operation is caused to be executed to program a set of data from the first memory die to the second memory die.

Abstract: A storage system has a memory with primary and secondary blocks. Data is stored redundantly in the primary and secondary memory blocks but in a different programming order. For example, data is programmed in the first memory block starting at a first wordline and ending at a last wordline, while data is programmed in the second memory block starting at the last wordline and ending at the first wordline.

Abstract: A storage system and method for smart folding are provided. In one example, the storage system has a memory with a plurality of single level cell (SLC) blocks and a multi-level cell (MLC) block. The MLC block has a plurality of pages, each with a different sense time. The storage system tracks a read count of each of the plurality of SLC blocks and determines how to fold the plurality of SLC blocks into the plurality of pages based on the read count of each of the plurality of SLC blocks and the sense time of each of the plurality of pages. In this way, SLC blocks with higher read counts can be folded into pages that have faster sense times.
