Abstract
A computer system and method for enabling memory expansion without shutting off the computer system are disclosed. The computer system has a dual memory configuration and supports memory insertion and extraction while being on-line. The memory content of one system may be copied to the memory of another system according to a predetermined priority or after a predetermined delay. Memory may be used efficiently during the insertion or extraction by securing a status management table expansion area in an expanded portion of memory. Memory may be expanded in computer systems that do not have an open memory slot by replacing the installed memory with a memory having a larger capacity.
