@p0lunin The AMD64 architecture defines a 64-bit virtual address format, of which the low-order 48 bits are used in current implementations.[11](p120) This allows up to 256 TiB (248 bytes) of virtual address space.

The Control Data 6600 (and its brothers) Central Processor used a 60-bit word, and could only address a word at a time. In one sense, a "byte" on a CDC 6600 was 60 bits.
