DRAM - DRAM SUB-ARRAY LEVEL AUTONOMIC REFRESH MEMORY CONTROLLER OPTIMIZATION

摘要

A method of refreshing a dynamic random access memory (DRAM) includes detecting an open page of a DRAM bank in a row of DRAM banks in an open sub-array of DRAM banks. The method also includes delaying the dispatch of the refresh command to the target refresh row of the DRAM bank when the target refresh row of the DRAM bank is within the open sub-array of the DRAM bank.
