Zusammenfassung:A system, method, and a computer readable for protecting content of a memory page are disclosed. The method includes determining a start of a semi-synchronous memory copy operation. A range of addresses is determined where the semi-synchronous memory copy operation is being performed. An issued instruction that removes a page table entry is detected. The method further includes determining whether the issued instruction is destined to remove a page table entry associated with at least one address in the range of addresses. In response to the issued instruction being destined to remove the page table entry, the execution of the issued instruction is stalled until the semi-synchronous memory copy operation is completed.
