Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a signaling can be received that indicates a request from a controller to migrate valid data from a first data block to a second data block. For example, the first data block can be a data block of a plurality of memory cells configured as single-level-cell (SLC) memory. The second data block can be configured as multi-level-cell (MLC) memory. The data migration operation can include an error control operation that is performed using the memory component, the error control operation excluding transferring the data to the controller. The data can be migrated from the first data block configured as SLC memory to the second data block configured as MLC memory after the error control operation is performed using the memory component.

Abstract: Systems, apparatuses, and methods related to data compaction in memory or storage systems or sub-systems, such as solid state drives, are described. For example, one or more memory pages storing valid data can be identified from a first data block in a plane of a memory component and copied to a page buffer corresponding to the plane. A controller of the system or sub-system can determine whether the plane of the memory component has another data block with capacity to store the one or more memory pages and can copy the one or more memory pages from the page buffer either to the other data block or to a different data block in a different plane of the memory component.
