Abstract:
An overlaid erase block (EB) mapping scheme for a flash memory provides efficient wear-leveling and reduces mount operation latency. The overlaid EB mapping scheme maps a first type of EB onto one of a plurality of physical erase blocks, in a corresponding portion of the flash memory. The first type of EB includes a plurality of pointers. The overlaid EB mapping scheme also maps each of second and third types of EBs onto one of the physical EBs that is not mapped to the first type of EB. The second type of EBs store system management information and the third type of EBs store user data. When the flash memory is started up, the overlaid EB mapping scheme scans the corresponding portion to locate the first type of EB, locates the system EBs using the pointers, and locates the data EBs using the system management information.

Claim (Index 38):
A system, comprising:\n at least one processor; at least one memory coupled to the at least one processor by a communication infrastructure; and at least one storage device coupled to the communication infrastructure and including a plurality of physical erase blocks (EB) that each include nonvolatile memory cells configured to be erased together, the physical EBs having a physical mapping that includes an overlay region and a non-overlay region, and including\n a plurality of data EBs configured to store data, \n first type system EBs configured to store system management information for the data EBs, and \n at least one second type system EB configured to store metadata for locating the first type system EBs; wherein \n the at least one second type system EB is restricted to the overlay region, and the data EBs and first type system EBs are not restricted to the overlay region.
