NAND overview: From memory to systems

Abstract

It was in 1965, just after the invention of the bipolar transistor by W. Shockley, W. Brattain and J. Bardeen, that Gordon Moore, co-founder of Intel, observed that the number of transistors per square centimeter in a microchip doubled every year. Moore thought that such trend would have proven true for the years to come as well, and indeed in the following years the density of active components in an integrated circuit kept on doubling every 18 months. For example, in the 18 months that elapsed between the Pentium processor 1.3 and the Pentium-4, the number of transistors grew from 28 to 55 million. © 2010 Springer Science+Business Media B.V.
