Abstract
Apparatuses, systems, and methods are disclosed for block reuse for memory operations. An apparatus may include one or more storage elements and a controller. A controller may be configured to manage a metadata structure and a metadata change structure. In certain embodiments, the metadata structure stores metadata relating to the one or more storage regions and the metadata change structure stores changes to be made to the metadata structure. A controller may be configured to perform an availability check to determine if one or more presently allocated storage regions identified in a metadata change structure are reusable. A controller may be configured to allocate one of a storage region from one or more presently allocated storage regions and a free storage region from a free memory group based on an availability check.
