DRAMs as model organisms for study of technological evolution

Abstract The short, well-documented market life of generations of dynamic random access memory (DRAM) computer chips makes them an excellent “model organism,” like the fruit fly, for study of evolution, in this case technological. Using classic models of logistic growth, substitution, and learning, we examine the global dynamics of eight generations of DRAMs and forecast the market characteristics of the next DRAM generations.
