Ten,

Pentium added an addressing mode which allows you to add large chunks of memory using small increments in the logical address. I don't have an exact reference with me, but it allows extension of a significant amount of memory past 32 bits. (It has been several years since I worked on x86 design.)

Tenchusatsu,

Logically, all processors starting with 386 can address 64 TB. The old segment-offset addressing of 8086 still exists in 386, with the only difference that the segment is be 4 GB instead of 64 KB

I have no idea how addressing this virtual memory is implemented in hardware.
