Inverted Page Tables

This lesson briefly explains the idea of inverted page tables and how it contributes to​ reducing​ the memory overhead of page tables.

An even more extreme space savings in the world of page tables is found with inverted page tables. Here, instead of having many page tables (one per process of the system), we keep a single page table that has an entry for each physical page of the system. The entry tells us which process is using this page, and which virtual page of that process maps to this physical page.
