text: # 45-bit computing
  
  In computer architecture, 45-bit integers, memory addresses, or other data units are those that are 45 bits wide. Also, 45-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
  
  ## Examples
  
  Computers designed with 45-bit words are quite rare. One 45-bit computer was the Soviet Almaz ("Diamond [ru]") computer.
