Memory controller with support for memory modules comprised of non-homogeneous data width RAM devices |
摘要 |
A memory controller that reads and writes memory modules populated with non-homogeneous data width RAM devices, wherein the RAM devices are of a type which send and receive data with a source synchronous strobe. The memory controller maintains a memory map and stores therein indications of data/strobe ratios which are required to read and write memory modules coupled to the memory controller. The indications of data/strobe ratios are addressed during read and write cycles of the memory controller. Addressed indications are used during write cycles to ensure that strobes are generated at a correct number of strobe pads. Addressed indications are used during read cycles to ensure that received data signals are associated with their correct and corresponding strobe signals.
