Abstract: Systems, methods, and data storage devices for dynamic mode selection for hybrid MLC/SLC data storage devices are described. Storage operations at a plurality of storage devices from a host device may be processed, wherein each storage device of the plurality of storage devices comprises a plurality of partitions including multi-level cell blocks and single-level cell blocks and multi-level cell blocks may be selectively written in a single-level write operation. A usage value is determined for each partition of the plurality of partitions at each storage device of the plurality of storage devices. A storage device of the plurality of storage devices may be dynamically selected based on the usage value for single-level cell blocks of the selected storage device having available single level cell blocks. New data may then be stored at the dynamically selected storage device of the plurality of storage devices.

Abstract: A multi-later memory and method for operation is disclosed. The memory includes at least one flash memory die having multiple layers and a controller configured to execute block reclaim operations in a layer of the flash memory die until a net gain of at least one additional free block has been made in the layer. The method may include relocating data from reclaim blocks to relocation blocks within the same layer, or within a same partition in the same layer until a net gain of one free block has been achieved and an integer number of relocation blocks has been filled with relocated data. The method may also include moving data from reclaim blocks in a first layer into destination blocks in a second layer until a net gain of at least one free block has been achieved in the first layer.

Abstract: Embodiments described herein disclose methods, devices, and media for storing data. Methods including the steps of: receiving data to be stored in a memory that includes at least three blocks, wherein each block, for storing the data, has at least one metadata value, associated with each block, that is dependent upon a writing time of each block; grouping at least three blocks into at least two block groups, wherein at least one block group contains at least two blocks; associating a respective metadata value with each block group; and associating the respective metadata value of a respective block group with each block storing the data contained in the respective block group, without storing a dedicated copy of at least one metadata value for each block. In some embodiments, at least one metadata value is stored in a block-group table.
