A carrier having at least one memory chip in a daisy chain of memory
chips. A first carrier has at least a portion of an entire daisy chain of
memory chips attached to the first carrier. An address/command bus input
on the first carrier carries an address/command word to a first memory
chip in the daisy chain of memory chips. If the first memory chip
determines that the address/command word is not directed to the first
memory chip, the first memory chip re-drives the address/command word to
a second memory chip in the daisy chain of memory chips using a point to
point address/command bus link. If there are no more memory chips on the
first carrier, the address/command word is re-driven to a memory chip on
a second carrier.
