Patent ID: 8412880

Claim:
A system controller and host interface (SCHI), comprising: a host interface; and a system controller communicatively coupled to the host interface, and having a number of memory interfaces, wherein the system controller is configured for controlling a plurality of intelligent NAND storage nodes (INSNs) communicatively coupled to the number of memory interfaces, each of the plurality of INSNs including a node controller communicatively coupled to a number of memory devices by an Open NAND Flash Interface, the system controller including logic configured to map between physical and logical memory addresses, and logic configured to centrally manage wear level across the entire plurality of INSNs communicatively coupled to all of the number of memory interfaces of the system controller collectively as a single memory system for wear leveling, and wherein centrally managing wear level includes detecting differences in wear between INSNs, between the number of memory devices associated with a particular INSN, and between memory devices associated with multiple INSNs.
