{{Computer architecture bit widths}}

In [[computer architecture]], '''26-bit''' [[integers]], [[memory address|memory addresses]], or other [[Data (computing)|data]] units are those that are 26 bits wide, and thus can represent unsigned values up to 64 mega (base 2)67,108,863. Two examples of computer processors that featured 26-bit memory addressing are certain second generation IBM [[System/370]] [[mainframe computer]] models introduced in 1981 (and several subsequent models), which had 26-bit physical addresses but had only the same 24-bit virtual addresses as earlier models, and the first generations of [[ARM Limited|ARM]] processors.
