==={{anchor|LPAE}}Large Physical Address Extension (LPAE)===
The Large Physical Address Extension (LPAE), which extends the physical address size from 32 bits to 40 bits, was added to the Armv7-A architecture in 2011.<ref>{{cite book |title=ARM Architecture Reference Manual, ARMv7-A and ARMv7-R edition |publisher=ARM Limited}}</ref>

The physical address size may be even larger in processors based on the 64-bit (Armv8-A) architecture. For example, it is 44 bits in Cortex-A75 and Cortex-A65AE.<ref>{{cite web |url=https://developer.arm.com/ip-products/processors/cortex-a/cortex-a65ae |title=Cortex-A65AE |website=ARM Developer |access-date=26 April 2019}}</ref>
