Abstract
An improved memory addressing system has a CPU having both an address bus and a multiplexed data/address bus. A reduced PIN out companion chip is coupled to the multiplexed data/address bus for decoding data and low order address information. Memory storage is coupled to a high order address bus for receiving a high order address from the CPU, and to the low order address bus and data bus for receiving decoded low order address and data information from the companion chip.
