Abstract
A fully mirrored memory system includes at least one split memory bus, with each portion of the split memory bus having active memory and mirror memory. Each portion of the memory bus transfers a portion of the data for a memory transaction. If a memory unit is determined to be defective, one portion of the memory bus may be inactivated for hot swapping of memory, and the system can continue to operate using an active portion of the memory bus.
