Chipkill is IBM's trademark for a form of advanced error checking and correcting (ECC) computer memory technology that protects computer memory systems from any single memory chip failure as well as  multi-bit errors from any portion of a single memory chip. One simple scheme to perform this function scatters the bits of a Hamming code ECC word across multiple memory chips, such that the failure of any single memory chip will affect only one ECC bit per word.
IBM's Chipkill is an advanced error detection and correction (EDC) computer memory technology aimed at safeguarding computer memory systems from failures in individual memory chips or multi-bit errors within a single chip. A basic strategy for this involves distributing the bits of a Hamming code EDC word across multiple memory chips, ensuring that the failure of any single memory chip impacts only one ECC bit per word.
