Abstract
A method of refreshing a dynamic random access memory (DRAM) includes detecting an open page of the DRAM at a row of a DRAM bank within an open sub-array of the DRAM bank. The method also includes delaying issuance of a refresh command to a 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.
