Abstract: An integrated circuit (IC) chip carrier includes one or more memory devices therein. The memory is integrated into the carrier prior to the IC chip being connected to the carrier. Therefore, the IC chip may be connected to the memory at the same time as the IC chip is connected to the carrier. Because the memory is integrated into the IC chip carrier, prior to the IC chip being attached thereto, reliability concerns that result from attaching the memory to the IC chip carrier affect the IC chip carrier and do not affect the yield of the relatively more expensive IC chip.
