Abstract:
A memory controller enters a memory mode, allocating memory address space within a pair of dual in line memory modules (DIMMs) such that each DIMM of the pair contains unallocated memory address space corresponding to allocated memory space in the other DIMM. The memory controller enters another memory mode, modifying the allocation of the memory address space from a first DIMM of the pair of DIMMs to a second DIMM of the pair of DIMMs. The data is moved from allocated memory address space of the first DIMM to unallocated memory address space in the second DIMM.
