With PAE,IA-32architecture is augmented with additional address lines used to select the additional memory, so physical address size increases from 32 bits to 36 bits. This increases the physical memory addressable by the system from 4 GB to 64 GB. The 32-bit size of the virtual address is not changed, so regular application software continues to use instructions with 32-bit addresses and (in aflat memory model) is limited to 4 gigabytes of virtual address space. Operating systems supporting this mode usepage tablesto map the regular 4 GB address space into the physical memory, which, depending on the operating system, may be as big as 64 GB. Themapping is typically applied separately for eachprocess, so that the extra memory is useful even though no single regular application can access it all simultaneously.
