Well memory hogs, AMD has it for you - the 27C1024 CMOS EPROM. That's
right, a megabit on a chip. It's organized as 65536 words by 16 bits.
It comes in a 40-pin package. Access time is speced at 170nS. And
it can be programmed in 49 seconds! It uses 1.5 um CMOS technology 
resulting in a die under 80,000 square mils. It should be in full 
production by third quarter 1985. No price info; but figure $200.00
or so through 1985 and 1986.

Plus, they think the memory cell size can be shrunk even more yielding
multi-million bit devices.
