Avoid cache lookup for cold cache

An electronic device, comprising:

• a processor having one or more processor cores;
• the processor to:
• receive, in a read/modify/write (RMW) pipeline, a cache access request from a requestor, wherein the cache access request comprises a cache set identifier associated with requested data in a cache set;
• and
• determine whether the cache set associated with the cache set identifier is in an inaccessible state or an invalid state, and in response to a determination that the cache set is in an inaccessible state or an invalid state, to:
• terminate the cache access request;
• and
• a computer readable memory communicatively coupled to the processor.
