Abstract
Disclosed is a storage system. The storage system includes a redundant array of inexpensive disks (RAID) controller. The RAID controller includes a flash memory controller coupled to a flash memory. The flash memory controller may perform background management tasks. These include logging and error reporting, address translation, cache table management, bad block management, defect management, wear leveling, and garbage collection. The array controller also allows the flash memory to be divided into multiple mappings.
