Abstract: A method and controller for operating a memory system in communication with a host. The method and controller logically arrange a sequence of reclaim sub-groups within a memory device. The method and controller process the reclaim sub-groups according to the sequence to control the memory device to perform garbage collection on the reclaim sub-groups in the memory device. In the sequence, the reclaim sub-groups are processed during the garbage collection such that at least one re-ordered data sequence in the sequence of the reclaim sub-groups being processed has re-ordered valid data that is not clumped.

Abstract: A device and related method, the device including memory, communications circuitry, and processing circuitry. The processing circuitry allocates processing bandwidth of the device to process the received instructions and executes the instructions based on the allocated processing bandwidth using a first amount of free memory. If the used first amount of free memory is at least a first threshold, processing circuitry reduces the allocated processing bandwidth to process the received instructions based on the used first amount of free memory and continues to execute the instructions based on the reduced allocated processing bandwidth using a second amount of free memory of the device. If the used second amount of free memory is at least a second threshold, processing circuitry further reduces the allocated processing bandwidth to process the received instructions based on the used second amount of free memory, and allocates processing bandwidth to perform garbage collection of the memory.
