Intel® 855PM Chipset Memory Controller Hub (MCH) Datasheet
The Intel® 855PM MCH is an Intel® Centrino® processor technology component. The MCH manages the flow of information between its four interfaces: the processor side bus, memory interface, AGP interface, and hub interface. The MCH arbitrates between the four interfaces when each initiates an operation. The Intel 855PM memory controller hub (MCH) is designed for use with the Intel Pentium M processor/ Intel Celeron M processor.
