Abstract

The mapping of system memory addresses to physical memory addresses is modeled as a two dimensional mapping array. Each element of the mapping array is assigned a system memory address and a physical memory address to which the system memory address is mapped. The mapping array is arranged to facilitate designation of a portion of the physical memory addresses as spareable physical memory addresses that are employed when there is a memory failure.
