Abstract
A data processing system includes a dynamic random access memory (DRAM), a prefetcher, and a refresh controller. The DRAM includes a plurality of DRAM cells, each with a capacitive storage element. The prefetcher is configured to prefetch information from the DRAM into a prefetch buffer in accordance with a prefetch pattern of addresses in the DRAM. The refresh controller includes a dynamic refresh control circuit configured to detect prefetch patterns of the prefetcher, and, in response to a detected prefetch pattern, refresh locations of the DRAM in accordance with a refresh pattern of addresses which is based on the prefetch pattern of addresses.
