I seem to remember that the manufactures oopsed and built too much capacity. No real idea why though. Other neurons firing give rise to the fleeting thought that Japanese and US chip companies got blindsided by the Korean? entry into the market.<p>I do know that circa 1995 suddenly there was a plethora of CMOS analog chips on the market taking advantage of otherwise idle CMOS lines. Later analog IC companies made good use of obsolete DRAM&#x2F;CPU production lines.<p>I wouldn&#x27;t use any of the above as TRVTH though.
