However, remember we are talking _roms_ and not either RAMs or EPROMs. With 1u Technology you can build a diode in a little bit over 1.8 u square. With two level metal CMOS that is potentially 250,000 bits per square mil and 8M bits in about 33.5 sq mils. Drivers, row and column decoders and the selection circuits will add some space but it isn't inconceivable at all. Just remember you don't need any transistors/cell in a masked rom and it makes more sense. I suppose someone could always call Toshiba or someone and ask. :-) -- --Chuck McManis Sun Microsystems uucp: {anywhere}!sun!cmcmanis BIX: Internet: cmcmanis@Eng.Sun.COM These opinions are my own and no one elses, but you knew that didn't you.
