Abstract

A method and system for optimizing use of signal paths on a DRAM interface. Signal paths that have a ‘don't care’ status during DRAM refresh are assigned to communication with another device. Onset of the refresh procedure triggers diversion of shared signal paths away from the DRAM to the other device for the duration of the refresh the shared signal paths include at least some of the address and data signal paths.
