Abstract
The present disclosure describes DRAM architectures and refresh controllers that allow for scheduling of an opportunistic refresh of a DRAM device concurrently with normal row activate command directed toward the DRAM device. Each activate command affords an 'opportunity' to refresh another independent row (i.e., a wordline) within a memory device with no scheduling conflict.
