Abstract
A computer system has a system memory, cache memory, system controller that process memory transactions. The system controller transmits a memory request to the system memory without waiting for the cache memory to be snooped to determine whether the cache memory stores information in an address corresponding to a selected address of the system memory. The system controller may transmit a snoop request to the cache memory concurrently with or after the memory request is transmitted to the system memory. The system controller may have a control switch that uses a first pathway for the memory request and a second pathway for the snoop request so that the snoop and memory requests can be transmitted simultaneously.
