发明名称 Deferring refreshes during calibrations in memory systems
摘要 A method, an apparatus, and a computer program are provided to control refreshes in Extreme Data Rate (XDR(TM)) memory systems. XDR(TM) memory systems employ calibrations to ensure the precise transmission of data. During calibrations, memory refreshes can occur; however, these refreshes can interfere with calibration streams. Therefore, to alleviate collisions and interferences, refreshes are deferred to periods where no calibrations are taking place. The number of deferred refreshes is also tracked such that the overall loss of refreshes is prevented.
