Hi Folks-- I've already checked most of the web pages and sources mentioned on the list--so I am looking for possibly unlisted or little known sources--or stuff too new to be in the search engines or web sites. Heres my wish list: Static Ram--Flash is NOT acceptable for technical reasons "infinite" r/w life at 100ns write cycle (mandatory) Parallel address and data lines (sorry-not interested in serial) Maximum capacity per chip--512KBytes (not bits) or greater preferred 5 volt preferred, 3.5 will work in a pinch Very low power, with uA draw to maintain memory in backup/sleep mode VERY small package--standard 32 pin TSOP is TOO big. Need Ball Grid or ??? Target is build 4-16 MegaBytes in a module that will fit in a 1/2" diameter tube--so a production module of some sort might work too. Standard SIMM type modules are probably too big, but would be of interest for another project. Final size and weight is important--smaller is better! This will be flown in a small rocket (5-12" diameter). Also, Any one have fabrication experience with BGA devices?? Kelly William K.
