I need help identifying a DRAM. According to the local IBM clone store, it is a 256Kx4 80 ns DRAM. I need to know whether it is CMOS or NMOS, or at least who the manufacturer is, so I can call them. The runes on the chip are: AAAIM304P-08 NMBS 9051 (The I's might possibly be 1's and v.v.) I could not find the answer in the MIT engineering library, so I though I'd ask the People Who Know. Thanks for your help! rjw@space.mit.edu \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

This is made by NMB semiconductor, the NMB part number is AAA1M104 which is a 256K*4 80 nS fast page mode DRAM, Toshiba eq. is b+jwwg7vw is TC514256, This is a CMOS DRAM W*jwwwwv

I have in front of me a ceramic PGA chip that has 299 pins on it - in a 20x20 array, with a 10x10 space in the middle and a missing index pin. It's marked ^ <- that's a triangle L1A5057 SUPER-XBAR 4000448 TAC 9005 Actually, I have a half-dozen of these that I picked up surplus. What is it and who made it? - Brian
