Abstract

See full text

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.
