Bocs, igazad van. SRAM != SDRAM. :)

Viszont az IBM meresei szerint DRAM-ban is okozhat hibat:

"One example of the magnitude of the cosmic ray soft error phenomenon 
demonstrated that with a certain sample of non-IBM DRAMs the soft error 
rate as measured under purely real life conditions, and with the benefit 
of millions of device hours of testing, the soft error rate at sea level 
was measured at 5950 FIT per chip."
