SYSTEM AND METHOD FOR HIDDEN-REFRESH RATE MODIFICATION

摘要

A system (200) and method for modifying a hidden-refresh rate for dynamic memory cells (21GD) includes monitoring a control signal (CE*) from a processor (202) and performing a hidden-refresh of the dynamic data at a first refresh rate when the control signal (CE*) 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 (206) couples to the array of dynamic memory cells (216D) during a hidden-refresh of the array of dynamic memory cells. The hidden-refresh controller (206) is further configured to monitor a control signal identifying a request from a processor at the memory device and refresh the dynamic data a first refresh rate when the control signal is asserted. The hidden-refresh controller (206) is further configured to refresh the dynamic data at a second refresh rate when the control signal (CE*) is deasserted for a predetermined duration.
