System and method for unlocking additional functions of a module

Abstract

A system for interfacing with a co-processor or input/output device is disclosed. According to one embodiment, the system performs a maze unlock sequence by operating a memory device in a maze unlock mode. The maze unlock sequence involves writing a first data pattern of a plurality of data patterns to a memory address of the memory device, reading a first set of data from the memory address, and storing the first set of data in a validated data array. The maze unlock sequence further involves writing a second data pattern of the plurality of data patterns to the memory address, reading a second set of data from the memory address, and storing the second set of data in the validated data array. A difference vector array is generated from the validate data array and an address map of the memory device is identified based on the difference vector array.

Dependencies are inferred from the claim text.
