Claim:
1. An offline characterization system that generates, during an offline characterization phase prior to the operational lifetime of a flash memory chip, an optimal set of operating parameter values associated with a LUN in the flash memory chip, wherein the flash memory chip includes one or more LUNs, each LUN includes one or more blocks of flash memory and an associated set of one or more n-bit control registers, and each control register stores the value of an operating parameter associated with that LUN, the offline characterization system comprising: (a) a candidate generator that utilizes one or more predictive models to generate a candidate score for each of a plurality of potential candidates, wherein: (b) a hardware tester that: and (c) a candidate selector that selects the set of operating parameter values represented by the actual candidate with the highest hardware score as the optimal set of operating parameter values associated with the LUN.
