6.1 GeodeLink™ Memory Controller

The GeodeLink™ Memory Controller (GLMC) module sup-

ports the Unified Memory Architecture (UMA) of the

AMD Geode™ LX processor and controls a 64-bit DDR

SDRAM interface without any external buffering. The inter-

nal block diagram of the GLMC is shown in Figure 6-2.

The SDRAM memory array contains both the main system

memory and the graphics frame buffer. Up to four module

banks of SDRAM are supported. Each module bank can

have two or four component banks depending on the mem-

ory size and organization. The maximum configuration is

four module banks with four component banks, each pro-

viding a total of 16 open banks with the maximum memory

size supported being 2 GB.

The GLMC handles multiple requests for memory data

from the CPU Core, the Graphics Processor, the Display

Controller, and the external PCI bus via the GeodeLink

Interface Units (GLIUs). The GLMC contains extensive

buffering logic that helps minimize contention for memory

bandwidth between the various requests.
