The History of DRAM Circuit Designs – At the Forefront of DRAM Development –

Dynamic random-access memory (DRAM) has been the only high-density RAM used for over 30 years despite many attempts to replace it. Contributing to IT advances to this day, it has achieved an unprecedented six-fold increase in memory capacity in the last three decades. The author surveys the history of DRAM circuit design in this paper, based on his career at the forefront of DRAM development from its inception in 1970 through the present.
