发明名称 Method and apparatus for idle cycle refresh request in DRAM
摘要 Generally, methods and apparatus are provided for idle cycle refresh request in a dynamic random access memory. According to one aspect of the invention, a dynamic random access memory is refreshed by determining if a refresh of the dynamic random access memory is required; and allocating an idle cycle sequence to refresh at least a portion of the dynamic random access memory only if the determining step determines that a refresh of the dynamic random access memory is required. A refresh flag can optionally be set if a refresh is required. The idle cycle sequence comprises one or more idle cycles. The idle cycle sequence can optionally be allocated within a predefined duration of the refresh flag being set. The step of determining step whether a refresh of the dynamic random access memory is required can be based on real-time or expected conditions.
