  • Computer memory system and method for cleaning data elements
    Patent number: 5287512
    Abstract: A method for cleaning data elements in a memory system accessible by a bus master. A first data element is transferred between the bus master and a fast memory while writing the first element to a dirty element register within the memory system. The first element is then cleaned by writing it from the register to a slow memory within the system without delaying memory access requests for the fast memory.
