In computer architecture, 20-bit integers, memory addresses, or other data units are those that are 20 bits wide, and thus can represent values up to 1 mega (base 2). One example of computer processors that features 20-bit memory addressing is the MSP430X which was introduced in November 2006 by Texas Instruments and is based on the 16 bit MSP430 model that was extended for all registers to 20 bit wide registers.
