Abstract
A method for wear leveling memory elements in a memory component of a memory subsystem is described. The method includes a memory subsystem receiving a write request that includes user data and a logical address, removing a next physical address from a next address queue, which stores physical addresses that are designated to be used for fulfilling write requests, and writing the user data to the next physical address in the memory component. Further, the memory subsystem locates, in a logical-to-physical table, an entry associated with the logical address of the write request and includes an old physical address that is mapped to the logical address of the write request. The memory subsystem adds the old physical address to a disposal address queue, wherein the disposal address queue stores physical addresses that are not designated to be used for fulfilling write requests.
