ABSTRACT:
A memory system is provided that increases the overall bandwidth of a memory channel by operating the memory channel at a independent frequency. The memory system comprises a memory hub device integrated in a memory module. The memory hub device comprises a command queue that receives a memory access command from an external memory controller via a memory channel at a first operating frequency. The memory system also comprises a memory hub controller integrated in the memory hub device. The memory hub controller reads the memory access command from the command queue at a second operating frequency. By receiving the memory access command at the first operating frequency and reading the memory access command at the second operating frequency an asynchronous boundary is implemented. Using the asynchronous boundary, the memory channel operates at a maximum designed operating bandwidth, which is independent of the second operating frequency.
