In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, [1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro , and later by AMD in the Athlon processor. [ 2 ]
Physical Address Extension, an x86 computer processor feature for accessing more than 4 gigabytes of RAM; Power added efficiency, a percentage that rates the efficiency of a power amplifier; Post Antibiotic Effect, the period of time following removal of an antibiotic drug during which there is no growth of the target organism
A workaround first developed in the Pentium Pro, known as Physical Address Extension (PAE), allows certain 32-bit operating systems to access up to 36-bit memory addresses, even though individual programs are still limited to operating within 32 bits of address space. Provided there is enough memory installed, each program can have its own four ...
Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. [3] [4] x86 processors prior to the Pentium Pro have 32 or fewer physical address bits; however, most x86 processors since the Pentium Pro, which was first sold in 1995, have the Physical Address Extension (PAE) mechanism, [5]: 445 which allows addressing up to 64 GiB (2 36 words) of memory.
Added 36-bit physical memory addressing, "Physical Address Extension (PAE)". Pentium M : updated version of Pentium III's P6 microarchitecture designed from the ground up for mobile computing and first x86 to support micro-op fusion and smart cache.

An overhead of 1 KiB of memory is required for maintaining page directories and page tables. When accessing this 1 MiB memory, each of the 256 page entries would be cached in the translation lookaside buffer (TLB; a cache that remembers virtual address to physical address translations for faster lookup on subsequent memory requests). Cluttering ...
