DRAM market by successive generation and total market volume (in bits, logarithmic scale). Bold lines are empirical data; thin dashed lines are model estimates (based
on the model described in the previuos illustration and a regressive exponential model of market volume growth). The overall fit of this simple model is reasonable,
although the model does not capture the delayed phase out of some DRAM generations (e.g., of the 1Mbit DRAM), indicating the additional influence of intricate marketing and pricing strategies.
