I quoted the MK4116, manufactured by Mostek, which according to Wikipedia:
In 1976 Mostek introduced the silicon-gate MK4027 (an improved version of the metal-gated MK4096), and the new MK4116 16kb double-poly silicon-gate DRAM. They were designed by Paul Schroeder, who later left Mostek to co-found Inmos. From this point until the late 1970s Mostek was a continual leader in the DRAM field, holding as much as 85% of the world market for DRAM. The MK4027 and MK4116 were reverse-engineered by Mosaid and successfully cloned by many companies.
I don't really see any point in further dialogue on this topic.
So what. . . you post a bunch of blather about a single component that is required to make the actual RAM, not the working RAM. You really do not seem to understand the complete cost involved, do you? It is NOT the single component chip. . . it is making it WORK that costs the money. You are delusional if you think you can just through eight chips in a box and it works. Sorry, Diogenes. YOU ARE WRONG.
I don't care how much of the market Mostek held in the DRAM chip market, it still would not be working RAM until you combined it with other chips, circuit boards, etc, and THEN you'd have working RAM. . . which cost approximately $400-$500 or so. I don't give a flying Fish that you could buy the COMPONENT DRAM for x dollars, it would STILL NOT WORK until it was made into a finished, working product!
YOU have a problem grasping that. I, as an Economist, don't have a problem at all. YOU DO!
