A recently granted patent (Publication Number: US11886334B2) discloses a method for managing memory in a storage system using nonvolatile random-access memory (NVRAM). The method involves allocating virtual units of NVRAM corresponding to physical memory, writing data of various sizes into these allocated units, and relocating data to free up space in certain virtual units for reallocation. The process includes defragmenting the NVRAM by moving data within the memory and tracking correspondence between virtual units and physical memory addresses.

Furthermore, the patent describes the use of tangible, non-transitory, computer-readable media with instructions for executing the memory management method. It also details a storage system comprising NVRAM, solid-state storage memory, and a processor to perform the memory management method. The system involves allocating virtual units of NVRAM, writing data into these units, and relocating data to make space available for further allocation. The method includes defragmenting the NVRAM, tracking correspondence between virtual units and physical memory addresses, and involves multiple authorities handling data at different layers within the storage system.
