What do people know in this newsgroup about the latest available in memory and LCD technology? What is the densest ROM/EPROM you know of? How about RAM? Here is the hard one. What LCD is available that gives the most dots per inch in the smallest space? Who makes these, and where are they available? Billy Harvey wxh@lanl.gov

Here's my list of 'commonly available' stuff - it excludes things like 16 Mb DRAM chips which exist but I don't believe are yet for sale. If anyone knows differently, please correct me. EPROM: 4Mb: 512k x 8 DRAM: 4Mb: 1M x 4, 4M x 1 SRAM: 1Mb: 128k x 8 If you can't buy in volume from the reps, one source I found that has a very wide selection of memory devices is Microprocessors Unlimited (strange name since mostly they sell RAM :-), 918-267-4961. Their prices for the above are $55, $28, and $26. Hitachi has an 1120 x 780 LCD module with a dot pitch of 0.205 mm and dimensions of 316 x 230 x 31 mm (part # LMG9001ZZZ). I don't know if this is state of the art or what. I've seen some Canon FLC (ferroelectric LC) prototype displays which have much higher resolution but these are not yet in production. 640 x 480 displays are common, with dot pitches around .30 or less. -- Rainer Malzbender Dept. of Physics (303)492-6829 U. of Colorado, Boulder rainer@boulder.colorado.edu 128.138.240.246

One normally gets technology reviews at the end of the year, but I have to provide my management figures and facts NOW. What I'm after are state of the art figures and facts for CMOS and BiCMOS, and records, like how many transistors on a non-memory chip, etc. What I have at present : in excess of 1 million transistors on a CMOS processor (1.4 million ?), feature sizes of 0.8microns available with 0.4microns in the offing, CMOS processor speeds commonly around the 30MHz mark, with expected 50-60MHz speeds, and experimental around 450MHz, double layer (triple ?) metal interconnects are commonplace. Any information would be appreciated (largest gate arrays, impact of BiCMOS, complexity of mixed analog/digital chips, etc.) And yes, I know my local library might have all that info, but, no, I do not have access to my local library right NOW :-) I'd prefer email responses to a.guillaume@trl.oz.au, and if there is interest I could summarise to the net. Thanks in advance Andrew Guillaume a.guillaume@trl.oz.au
