An electronic module comprising a multiplicity of pre-stacked IC chips (30), such as memory chips, and an IC chip (34), referred to as an active substrate or active backplane, to which the access plane is directly secured. A multiplicity of aligned solder bumps (44) may interconnect the stack (32) and the substrate (34), providing electrical, mechanical and thermal interconnection. The active substrate is a silicon layer containing substantial amounts of integrated circuitry, which interfaces, on one side, with the integrated circuitry in the stacked chips, and, on the other side, with the external computer bus system. Some of the high priority circuitry which may be included in the substrate is used for control, fault-tolerance, buffering, and data management. |
