Crucial explains chip density, compatibility, and pricing

"Memory manufacturers are constantly striving to reduce their cost-per-bit while they migrate production to chips with greater densities. Today, we are capable of producing chips with densities of 256Mb and 512Mb. Crucial's parent company, Micron, is in a leading position in providing a 1 Gb chip. As manufacturers get more density (storage) per chip and migrate to newer processes, the production cost per megabit decreases."
So there you have it, put more in a smaller package and make tons of them. Thats how you make money in the mfg business.
