Abstract
A method of accessing a memory includes accessing multiple ECC words via a single memory channel. Portions of each ECC word are retrieved from different memory ranks, so that a failure in a memory device at one memory rank is less likely to result in uncorrectable errors in the data segment. By accessing the data segments via a single memory channel, rather than multiple memory channels, the single memory channel can be accessed independently, providing for lower cost memory modules, higher memory bandwidth, and lower power dissipation.
