Abstract
A method and apparatus for operation of a memory module for storage of a data word is provided. The apparatus includes a memory module having a set of paired memory devices including a first memory device to store a first section of a data word and a second memory device to store a second section of the data word when used in failure free operation. The apparatus may further include a first logic module to perform a write operation by writing the first and second sections of the data word to both the first memory device and the second memory device upon the determination of certain types of failure. The determination may include that a failure exists in the word section storage of either the first or second memory devices but that no failures exist in equivalent locations of word section storage in the two memory devices.
