Integrated memory controller
In a traditional processor design, the processor is connected to the front side bus and the Northbridge chip. The processor communicates with other system components through the front side bus. Smaller manufacturing size has reduced the overall size of a processor, leaving more room on the processor die for additional cores or cache. To improve performance, some processors include the memory controller on the processor die rather than in the Northbridge chip, resulting in faster memory access by the processor.
