Abstract
A system and device for expanding accessible memory of a processor is provided. An interposer is coupled to the processor and a memory module. The interposer is coupled to a first connection and a second connection. The interposer includes a memory controller circuit. The memory controller circuit receives signals from the processor, using the first connection, and transmits the received signals to the memory module, using the second connection. The interposer expands memory access without an unnecessary second processor.
Claims11
A system, comprising:
- a processor coupled to a first connection;
- a memory module coupled to a second connection;
- and
- an interposer coupled to the first connection and the second connection, the interposer including an optional interconnect module, socket pins, and a memory controller circuit, wherein the memory controller circuit receives signals from the processor, using the first connection, and transmits the received signals to the memory module, using the second connection, wherein the optional interconnect module protrudes from a top surface of the interposer and provides a copper-based high speed pluggable interface on the top surface of the interposer for plugging in a routing cable, and wherein the socket pins are located on a bottom surface of the interposer;
- and
- a first motherboard including two processor sockets, wherein the processor is connected to a first one of the two processor sockets, and the interposer is connected to a second one of the two processor sockets;
- and
- a second motherboard including another two processor sockets, wherein the interposer is connected to a second interposer using the cable, the second interposer installed on one of the another two processor sockets on the second motherboard using the cable.
An interposer for expanding accessible memory available to a processor, the interposer comprising:
- a circuit board;
- a package with socket pins insertable in a processor socket in a motherboard wherein the circuit board is bonded to the package and the socket pins are located on a bottom surface of the interposer;
- a high speed communication interface on the circuit board, the high speed communication interface including an optional interconnect module for cable routing, the optional interconnect module protruding from a top surface of the interposer and providing a copper-based high speed pluggable interface on the top surface of the interposer for plugging in a cable connector;
- a double data rate (DDR) communication interface on the circuit board;
- and
- a memory controller circuit that transmits signals received from the processor via the high speed communication interface to a memory module using the DDR communication interface;
- and
- wherein a cable connected to the optional interconnect module connects to a second interposer installed on one of the another two processor sockets on a second motherboard.
