Abstract

A memory address controller addresses two memories and selectively modifies an address before it is applied to the addressing input of one of the two memories. A bit of the address is used to indicate to the controller if the address is to be modified. The same address is applied unchanged to the addressing input of the other of the two memories by the memory address controller. In this manner the addressing range is expanded.
