Abstract
In a device having a memory accessed as multiple pages, two or more pages of the multiple pages having identical content are identified. While the two or more pages are being identified, other processes running in the device are allowed to use the two or more pages, including being allowed to change cache attributes of each of the two or more pages. The two or more pages are combined into a single combined page (e.g., a newly allocated page of the multiple pages), and a process page record having multiple entries pointing to the multiple pages is updated so that entries that previously pointed to one of the two or more pages instead point to the single page.
