A memory refresh system and method. The inventive system includesa mechanism for selectively refreshing elements of a memory arrayin response to signals from a conventional memory management system. In the illustrative application, the memory is dynamic randomaccess memory and the inventive system is adapted to provide for selective refresh of those DRAM memory elements to which data hasbeen or will be stored. This allows for the use of advantageous DRAM memory elements while minimizing the power consumption thereof. Consequently, the utility of DRAM memory elements is extended to a variety of power sensitive applications including cellular telephony and mobile computing. |
