This first-person account of the early days of semiconductor memory development is reprinted from the IEEE Transactions on Electron Devices, Vol ED-31, no 11, Nov. 1984, pp 1549-1555. In it the author explains how his invention of DRAM came about and he chronicles the evolution of DRAM technology from 1967 through 1984. In that period, he reports, there was a lot of circuit and architectural innovation in a very competitive environment, with little documentation in the public literature.
