Abstract
A set of related methods for detecting the existence and exact nature of any rearrangements and/or inversions of address lines and/or data lines to a memory device, relative to a second set of address lines and/or data lines to the same memory, are disclosed. Moreover, a set of related methods for correcting these relative rearrangements and/or inversions are disclosed. These methods allow meaningful access to memory shared by two or more devices using different address and data paths in the case where the relative nature of the address and data paths is unknown a priori. These methods of detecting and correcting such mismatches in separate address and data lines to shared memory may be implemented either in hardware or software or a combination of both.
