Abstract
The present invention relates to the architecture and operation of computer hardware memory logic, and in particular to a method and respective system for verifying hardware memory logic, wherein an Error Correction Code (ECC) is used for correcting single-bit or multi-bit errors when the ECC-bits cannot be accessed directly for a read or write process. The system and process employs the selection of data patterns that produce check bits that are all ones to ferret out errors in the ECC circuitry.
