Abstract: Memory space of a digital device may be configured for both instructions/data (op-code) and ECC or parity when required, otherwise the entire memory space may be configured for just the program instructions/data. A standard word width memory may be configured for ECC or non-ECC functionality, or parity or non-parity functionality, based upon a desired application. The last portion of the memory may be allocated for ECC or parity data rather then application code when an ECC or parity implementation is required. When an ECC or parity implementation is not required, the entire memory may be used for the application code. This allows a digital device and memory to be used in applications having different robustness (e.g., application code integrity) requirements without have to fabricate different digital devices.
