An arrangement for dynamically translating virtual address into absolute or physical addresses of items of data. Each virtual address includes a segment table number, a segment table entry, and a segment page number. Segment descriptors are stored in a central memory. The address of a particular segment descriptor may be calculated from the segment table number and the segment table entry. From the segment descriptor, a unique identification termed a logic page number may be calculated. The logic page number permits pseudo-associative access to a table containing a number of entries proportional to the number of physical pages of the main memory, allowing the physical address to be determined.
