Abstract
A computing apparatus has a mode selector configured to select one of a long-bus mode corresponding to a first memory size and a short-bus mode corresponding to a second memory size which is less than the first memory size. An address bus of the computing apparatus is configured to transmit an address consisting of address bits defining the first memory size and a subset of the address bits defining the second memory size. The address bus has N communication lines each configured to transmit one of a first number of bits of the address bits defining the first memory size in the long-bus mode and M of the N communication lines each configured to transmit one of a second number of bits of the address bits defining the second memory size in the short-bus mode, where M is less than N.
