jim,

All DRAM has bit failures due to background radiation. In smaller memory systems this is detected with parity and may be corrected in software. In large memory systems ECC is employed to both detect and correct errors.
These same methods are used for SDRAM, EDO DRAM, DDR ram.


I think the biggest disservice Intel did to the computer industry a few years ago was releasing chipsets that encouraged manufacturers to abandon parity/ecc memory.
