Abstract:
A DRAM and memory controller are coupled during driver training to reduce mismatches. The impedances of the system are controlled through a termination at the controller to yield improvements in timing margins. The coupling of the components on a shared electrical bus through adjustment of the termination values during training removes known offset issues.
