System, method and storage medium for merging bus data in a memory subsystem

摘要

A method for re-driving data in a memory subsystem. The method includes receiving controller interface signals and a forwarded interface clock associated with the controller interface signals at a memory module. The memory module is part of a cascaded interconnect system. The controller interface signals are sampled with the forwarded interface clock and the sampling results in the controller interface signals being latched into interface latches. The controller interface signals are then latched into local latches using a local clock on the memory module. The contents of the local latches along with the local clock are transmitted to an other memory module or controller in the cascaded interconnect system.
