Abstract: A memory system comprising memory modules including memory chips including integrated switching circuits. A memory controller coupled to the memory modules is configured to initiate memory accesses. When a switching circuit within a memory chip detects the memory access, the switching circuit routes the access to another memory module if the access is not directed to a memory chip of the receiving memory module, or processes the access locally if the access is directed to a memory chip of the receiving memory module. The memory controller and memory modules are coupled via bi-directional serial links. Each memory module may include multiple switching circuits, each of which may be coupled to fewer than all of the memory chips within the memory module. Switching circuits further include circuitry configured to de-serialize data prior to conveyance to a memory chip, and serialize data received from a DRAM chip prior to transmitting the received data.

Abstract: One embodiment of the present invention provides a system for detecting a valid clock signal at a clock receiver. The system operates by receiving a clock signal at the clock receiver, and directing the clock signal into a control input of a voltage-controlled variable resistor. Next, the system uses the voltage-controlled variable resistor to control a first current. A current mirror is then employed to create a second current from the first current. This second current passes through a resistor to produce a control voltage, which is amplified to produce a validity signal indicating whether or not the clock signal is valid. In one embodiment of the present invention, the system additionally uses at least one capacitor to filter out periodic fluctuations in the validity signal.
