FIELD: information technologies.
SUBSTANCE: invention is related to the field of memory control in computer, in particular to control of address mapping tables in system of virtual addressing. In computer system, which uses virtual memory, multiple versions of specified page are saved: version of catalogue, version of table and version of data. Version of data contains date, which, as software object presumes, must be saved in the page. Versions of catalogue and tables for page contain versions of page content, which was varied in a certain way to comply with limitation on address mapping chart used by system of virtual addressing. When the page is used by system of virtual addressing as a catalogue or table, then versions of catalogue or table for this page are used, accordingly. When the page is a target of query for reading, data version of this page is used.
EFFECT: expansion of functional resources.
