NMOS gave way to CMOS ( the "C" in 41256C)

So, in particular 41256 & 81257 DRAM chips are just different flavors of the same thing?

I use that link mostly for figuring out what ram simms are.

Thanks. Unfortunately it doesn't help much with these old chips. For starters, none of those numbers come close to matching what's silk screened on the chips I have from the 128K/512K. They do match some of the numbers on the SIMMs from my Plus & SE though.
