发明名称 SYSTEM AND METHOD FOR HIDDEN-REFRESH RATE MODIFICATION
摘要 A system and method for modifying a hidden-refresh rate for dynamic memory cells includes monitoring a control signal from a processor and performing a hidden-refresh of dynamic data at a first refresh rate when the control signal is asserted. The dynamic data is refreshed at a second refresh rate when the control signal is deasserted for a predetermined duration. A hidden-refresh controller couples to an array of dynamic memory cells during a hidden-refresh of the array of dynamic memory cells. The hidden-refresh controller is further configured to monitor a control signal identifying a request from a processor at a memory device and refresh the dynamic data a first refresh rate when the control signal is asserted. The hidden-refresh controller is further configured to refresh the dynamic data at a second refresh rate when the control signal is deasserted for a predetermined duration.
