摘要：
The present invention facilitates the Dynamic Random Access Memory (DRAM) refresh function in a less obtrusive manner than in the prior art. The present invention facilitates the refresh function during idle time when the DRAM is not busy handling read or write transactions. If insufficient idle time exists then the present invention will force a refresh operation thus ensuring that all memory cells are maintained in a properly charged state.
