An interconnect including an input couplable to a source, and an encoder coupled to the input. The encoder is configured to: group information that is received from the source via a same channel; size the grouped information to a common width; and apply protection to the sized grouped information.

Interconnection of protected information between components

The disclosed invention provides a structure and method for detecting address line (e.g., wordline, bitline) memory failures. In one embodiment, the method and structure comprise generating an address signature, by re-encoding an internally generated address signal from activated elements (e.g., wordlines) inside a memory array. The regenerated address signature may be compared with a requested memory address location. If the regenerated address signature and memory location are equal than there is no error in the memory array, but if the regenerated address signature and memory location are equal than an error is present in the memory array. Accordingly, re-encoding an address signature provides a closed loop check that a wordline and/or bitline, that was actually activated in a memory array, was the correct requested wordline and/or bitline, that no other wordlines or bitlines were also triggered, and that the wordline and/or bitline is continuous.
