ChipkillA memory module technology from IBM that, similar to RAID 3 for hard disks, spreads the bits across multiple memory chips. It can take bad memory chips offline when too many bit errors are encountered and also correct errors of several bits per module. Chipkill typically exceeds the error correction in ECC memory. Although often referred to as Chipkill, similar technologies from other vendors are Single Device Disable Code (SDDC) from Intel, Extended ECC from Sun and Chipspare from HP. See ECC memory and RAID.
