Abstract: Disclosed herein is an apparatus and method for processing write-on-copy for supporting a fork in a memory disaggregation system. The method includes, when a child process is generated in the event of a fork, processing the fork by copying a page table for disaggregated memory of a parent process to the child process and setting write protection on a page of the disaggregated memory; and processing write access to the write-protected page. Processing the write access may use at least one of a first handler corresponding to access to the write-protected page mapped to the page table, or a second handler corresponding to the write access to the write-protected page that is not mapped to the page table, or a combination thereof.
