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.
