The inventor of DRAM, Robert Heath Dennard, just died a few months ago and I was reading his obit and his history. I think the long and short of it is that DRAM is cheap. DRAM needs one transistor per data bit. Competing technologies needed far more. SRAM needed six transistors per bit for example. Dennard figured out how to vastly cut down complexity, thus costs.
