Abstract:
A method and system are provided for coupling a DRAM and a memory controller during driver training to reduce mismatches by controlling impedances within the system environment. A memory device initializes a bit level voltage on a data net. A driver impedance in a driving element in the controller is modified to yield improvements in timing margins.
