Apparatus, systems, and methods to manage memory operations are described. In one example, a controller comprises logic to receive a first transaction to operate on a first data element in the cache memory, perform a lookup operation for the first data element in the volatile memory and in response to a failed lookup operation, to generate a cache scrub hint forward the cache scrub hint to a cache scrub engine and identify one or more cache lines to scrub based at least in part on the cache scrub hint. Other examples are also disclosed and claimed.
