Paging is a DRAM memory management method used by computers that allows data to be saved and obtained from a specified storage space to be used in the main memory. Under this method, data is gathered using blocks of the same size (called pages), which allows for noncontiguous use of the physical address space. When accessing memory within the same row the computer keeps the row address and only changes the column. Paging helps avoid fragmentation, reduces power consumption, allows for faster access, and resolves other problems that can be caused when the physical address space is used contiguously. Computer memory that uses this method is called Page Mode or Fast Page Mode, which is sometimes abbreviated as FP or FPM.
