Abstract:
A technique relates to operating a memory controller. The memory controller drives first memory devices and second memory devices of the memory controller in a dual channel mode. A first error correcting code (ECC) memory device and a second ECC memory device protect the first memory devices and the second memory devices. The memory controller drives the first memory devices and the second memory devices in a single channel mode such that the second ECC memory device is a spare memory device, and the first ECC memory device protects the first memory devices and the second memory devices. The memory controller is configured to switch between the dual channel mode and the single channel mode.

Claim (Index 18):
A method of switching from dual channel mode to single channel mode, the method comprising:\n determining, by a memory controller, that a switch is needed from the dual channel mode to the single channel mode of operating a memory module, wherein the memory module comprises memory devices on a first channel and a second channel; and switching, by the memory controller, from the dual channel mode to the single channel mode, which comprises:\n reading out all data from the memory devices of the memory module, \n loading the data from the memory devices of the memory module into a storage, \n causing a spare ECC memory device of the memory devices to be available by protecting the first and second channels with a single error correcting code (ECC) memory device instead of two ECC memory devices of the memory devices, \n mapping input and output of a failing memory device to the spare ECC memory device such that intended writing to and reading from the failing memory device is instead written to and read from the spare ECC memory device, and \n writing the data from the storage back to the memory devices of the memory module such that a portion of the data intended for the failing memory device is instead written to the spare ECC memory device.
