Communication bus system between processors and memory modules

摘要

An apparatus (10) is provided for address and data distribution to memory modules (20) . The apparatus (10) includes a controller (12) for controlling memory modules that comprises an optical transmitter (14) and a receiver (24). An optical cable (16) having a plurality of optical fibers (18) is connected to the optical transmitter (14) of the controller (12). A plurality of memory modules (20) are each connected to one of the optical fibers (18) and have a driver for transmitting data. A communication bus (22) is connected to the drivers of the memory modules (20) and to the receiver (24) of the controller (12). The controller (12) is operable to broadcast address and data information to the memory modules (20) via the optical fibers (18), and the memory modules (20) are operable to transmit data to the controller (12) via the drivers and the communication bus (22). <IMAGE>
