ABSTRACT:
A computer system includes a memory subsystem with a failover memory adapted to replace a memory module in the main memory when the main memory module fails or experiences an unacceptable level of errors. Upon the detection of the fault condition, a hot swapping of information from the module in the main memory may be accomplished to a module in an auxiliary memory. A state machine may supervise the transfer such that information which may have been written to the faulty memory during the transfer can be subsequently provided to the auxiliary memory. In this way, a fault condition can be corrected without decreasing the available system memory and without necessitating rebooting.
