Method and apparatus for caching mte and/or ecc data

A method for validating verification data comprising:

• receiving a memory request with associated memory request verification data at a cache memory, the cache memory storing verification data;
• querying the cache memory for stored verification data corresponding to the memory request verification data;
• responsive to the cache memory not containing stored verification data which corresponds to the memory request verification data, designating a cache miss;
• responsive to the cache miss, retrieving a burst of validation data from a main memory and populating the cache memory with the burst of validation data from main memory;
• responsive to the cache memory containing stored verification data which corresponds to the memory request verification data, comparing the stored verification data to the memory request verification data;
• responsive to a match between the stored verification data to the memory request verification data, validating the memory request verification data.

A system for caching verification data comprising:

• a bus configured to carry a data request, the data request including requested data and data request verification data that includes an address for the data request verification data;
• a cache memory containing stored verification data associated with an address, the cache memory configured to:
• receive the data request verification data;
• retrieve stored verification data based on the address;
• compare the stored verification data to the verification data associated with the data request;
• responsive to a match between the stored verification data and the data request verification data, validating the data request verification data;
• and
• responsive to validation of the data request verification data, provide the requested data to the bus.
