Advanced Memory Buffer(AMB) DRAM Interface Specifications
Plsease refer to the AMB Specification for all technical requirements
The following specifications for the AMB constitute the subset which is critical for proper operation of the
DDR2 SDRAM interface.
Note:
This list is not complete, more information will follow in later revisions of this specification.
Critical AMB Specifications
Note 1:
