SDRAM soft error rates

[estaub]

I'm trying to determine whether to use ECC SDRAM on a system, and am trying to find info on SDRAM soft error rates for modern SDRAM chips. I can't find anything newer than 1998. Can anyone refer me to some relevant data? If the old rates from 256Mb parts (~2/year) still holds true, we should be seeing soft errors every few weeks on most systems, and every few days at high altitudes - why don't we? Or do we?

You can check IEEE or it papers.
