The FPGA That Wasn’t
There was once a company which made a new kind of programmable logic device which they called Electrically Reprogrammable Arrays.
ERAs had an array of NAND gate cells and programmable interconnections repeated across the chip with an architecture similar to gate arrays allowing users to carry out their own gate array customising – on and off-line – so providing a low-cost route to ASIC.
The company licensed the technology to some of the glitterati of the semiconductor industry: Motorola, Toshiba. Plessey et al.
But no one could get it to market.
Moral: All that glisters is not gold.
