Fable: David and Goliath
Many years ago a typical memory device was a foot square and weighed a pound.
Then, in late 1970, along came a chip which was 10 mm square and did the same job.
When it was first made the chip yielded poorly – one or two die per 2 inch wafer using an 8 micron process – but this got solved.
The chip sold for the same price as its foot square competitor – one cent per bit.
The chip was accessed in nanoseconds whereas its big competitor accessed in milliseconds.
Nevertheless Goliath didn’t die instantly because he was nonvolatile and David was not, and because people didn’t trust MOS much.
But, eventually, he died.
Moral: Sic transit gloria corea
