Rambus Inc.
Cross-threaded memory system

Abstract:

A multi-chip package includes a logic integrated circuit (IC) die formed with plural memory controller circuits, a first memory IC die and a second memory IC die. The second memory IC die is mounted to the first memory IC die. The first memory IC die and the logic IC die are mounted to one another. The logic IC die includes a serial link interface for coupling to multiple serial links. The first memory die includes a first memory group accessed by a first one of the plural memory controller circuits, and a second memory group accessed by a second one of the plural memory controller circuits.
