    Under certain conditions this is possible. If the bad memory was modified
    then you have a condition that requires termination of all processes that
    are using the memory. If its the kernel then you need to reboot.

    If the memory contains a page from disk then the memory can be moved
    elsewhere.

    If you can clean up a whole range like that then its possible to replace
    the memory.
