Overlaid erase block mapping

A system, comprising:

• a memory including a plurality of physical EBs;
• and
• an EB mapping module configured to:
• map a first type of EB, which include pointers, onto one of the physical EBs, in a corresponding portion of the memory, and
• map each of second and third types of EBs onto one of the physical EBs that is not mapped to the first type of EB, wherein:
• the second type of EBs store system management information, and the third type of EBs store user data.

A tangible computer-readable device including a plurality of physical EBs and having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform EB mapping operations comprising:

• mapping a first type of EB, which includes pointers, onto one of the physical EBs, in a corresponding portion of the computer-readable device;
• and
• mapping each of second and third types of EBs onto one of the physical EBs that is not mapped to the first type of EB, wherein:
• the second type of EBs store system management information, and
• the third type of EBs store user data.
