5. Although normally credited with the first design of a DRAM, Advanced Memory Systems did not have the process technology to build a commercially viable chip. Intel did.
6. To read or store information in RAM, the computer must send an address signal through pins protruding from the chip. In the first DRAMs, the number of pins increased rapidly as the bit density of the chip increased. Mostek’s multiplexed addressing allowed the DRAM to have considerably fewer address pins even as density increased, making DRAM packages a lot smaller and simpler.
7. Utterback and Abernathy developed the concept of “dominant design,” a design whose major components and underlying core concepts do not vary substantially from one product model to the other and which commands a high percentage of the market share. See:

17. One reason often given for IBM choosing the Intel design is that Intel had a version of its 16-bit design (the 8088) that could use the older and cheaper 8-bit complementary chips. Since IBM wanted a low-cost PC, it chose Intel’s 8088.
18. This is a layer of instructions embedded in the microprocessor hardware that helps execute instructions from a computer’s instruction set.
19. AMD acquired NextGen, and, in early 1997, it appeared to be posing the first real threat to Intel’s dominant position in microprocessors. Its goal was to gain 30 percent of the microprocessor market share.

23. Enticing to competitors, Intel’s profits for 1995 were estimated at more than $3.5 billion, suggesting that the company has even more money to block competition.
24. The only other U.S. firm producing DRAMs, TI, did so outside the U.S. in a Japanese fab, using a Japanese design. Motorola signed an agreement in November 1987 to package and distribute Toshiba DRAMs.
25. Unlike microprocessors, DRAM does not have microcode that is protected by U.S. copyright laws. Appropriability of DRAM patents is weaker.
