Data located in data management units associated with the first indicator and the second indicator or between the first indicator and the second indicator are either copied to data management units of the destination group of data management units or remain located in data management units of the source group of data management units.

Following execution of the subset of the host read operations and the host write operations, the processing device executes an internal management traffic operation based on the predetermined proportion.

Abstract: Devices, methods, and media are described for unmap support in coarse mapped storage. In one embodiment a controller of a memory sub-system manages a set of metadata for super management units (SMU) of the memory sub-system, wherein each SMU of the memory sub-system comprises a plurality of data management units (MU), and wherein each MU comprises a plurality of addressable memory elements as part of a coarse memory storage of the memory sub-system. The controller processes a trim command for a first SMU of the plurality of SMUs, and adjusts a trim bit associated with metadata for the first SMU. This trim bit can then be used to manage read and write operations as the trimmed unit waits to be written with an unmap data pattern. Similarly, a trim bit in MU metadata can be used manage related operations to prevent memory access errors.
