A memory system stores user data including file content in clusters of memory space, folder entries, metadata, and a file allocation table FAT including FAT entries. The system comprises a cache memory, an addressable memory including memory space, and control logic coupled to the addressable memory and the cache memory. The control logic is configured to store user data in a current cluster at a current cluster offset including file content, and corresponding metadata including the current cluster offset, and a linked cluster offset of a linked cluster linking to the current cluster in the addressable memory, and to cache a FAT entry pointing to the current cluster in the cache memory.
