Claim 14:
15. A method performed by an integrated circuit (IC) device, comprising:
issuing, by a requesting agent, a first memory write transaction to access a first memory location;
determining, by a write cleaner circuit, that the first memory write transaction triggers a first clean request, the write cleaner circuit coupled to the requesting agent;
generating, by the write cleaner circuit, the first clean request to a write-back (WB) cache memory based on the first memory write transaction, the WB cache memory coupled to an interconnect fabric; and
in response to the first clean request, by the WB cache memory:
requesting a system memory to update the first memory location; and
updating a status of a first cache line corresponding to the first memory location from dirty to clean.
