摘要： Systems and methods for a DRAM concurrent refresh engine with processor interface. In exemplary embodiments, memory cells requiring periodic refresh at least once each for a specified refresh interval and words of an array organized banks in which the banks are selected for access by a bank-enable signal, each bank having a word decoder accepting one of two refresh word addresses, one refresh word address for a normal access, and the other for a refresh access, one of the word addresses selected by two separate enable signals, provided by on-macro refresh logic, which includes instructions to select one bank for refresh when no normal access occurs and select one bank for refresh concurrently with a normal access having no bank conflicts, the refresh logic maintaining the refresh status, timing of the refresh interval, and insuring all memory cells are refreshed within the refresh interval.
