IBM announced the first 512 kilobit microchip on this day in 1983. It was impossible to create a chip of such magnitude before this, but IBM created a new manufacture process called plate pushing to develop the new chip. The 512K chip was only an experimental version, and was not yet considered commercially feasible to manufacture; in fact, the 256 kilobit chip (previously the largest chip available) had not yet made it to market when this announcement was made.
