One embodiment of the present invention provides a method for rapidly determining whether a bank conflict exists during a memory access. The method operates by receiving an address as part of a memory access operation, and using the address to identify a target bank of memory to which the memory access operation is directed. The method next looks up an entry for the target bank of memory in a bank conflict table. This bank conflict table includes an entry for each bank of memory in the computer system. Each entry indicates whether a corresponding bank of memory is presently busy servicing a memory request. If the entry indicates that the target bank is not busy, the method immediately issues the memory access operation to the target bank of memory. Otherwise, the method stalls the memory access operation until the target bank becomes available. In one embodiment of the present invention, the act of issuing the memory request includes setting an entry corresponding to the target bank of memory in the bank conflict table so that subsequent memory access operations will detect that the target bank of memory is busy.
