Abstract
An improved method of accessing dynamic random access memory (DRAM) banks during refresh cycles contemplates sequentially accessing DRAM banks which do not share common filtering capacitors. In this manner, voltage drops caused by refresh accesses are not observed in consecutive clock cycles at the same filtering capacitors so that the filtering capacitors will have sufficient recovery time to restore the supply voltage to the original voltage level before another refresh hit occurs at the same capacitor. In this manner, significant voltage drops are alleviated at the voltage supply inputs to the DRAM banks.
