WebPage size varies from one architecture to the next, although most systems currently use 4096-byte pages. The constant PAGE_SIZE (defined in ) gives the page size on any given architecture. If you look at a memory addressâ virtual or physicalâ it is divisible into a page number and an offset within the page. Web512 K page size for x4 devices: reduces power (less activation power), and extends the usefulness of x4 devices, which allow for more efficient EDC solutions for high-end systems Programmable refresh: Reducing performance penalty of dense DDR4 devices by allowing for refresh intervals ranging from 1x to .0625x the normal refresh interval

A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in the page table. It is the smallest unit of data for memory management in a virtual memory operating system. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system.
