ABSTRACT:
A computer system includes a memory device on the first data bus, a requesting device that initiates a delayed memory read transaction on a second data bus, and a bridge device that delivers the delayed memory read transaction to the first data bus and receives from the first data bus completion data requested in the memory read transaction. The bridge device includes a data storage buffer that stores the completion data, and a buffer management element that automatically requests from the memory device additional data to be placed in the data storage buffer.
