Abstract:

A system including a host coupled to a serially connected chain of memory modules. In one embodiment, each of the memory modules includes a memory control hub for controlling access to a plurality of memory chips on the memory module. The memory modules are coupled serially in a chain to the host via a plurality of memory links. Each memory link may include an uplink for conveying transactions toward the host and a downlink for conveying transactions originating at the host to a next memory module in the chain. The uplink and the downlink may convey transactions using packets that include control and configuration packets and memory access packets. The memory control hub may convey a transaction received on a first downlink of a first memory link on a second downlink of a second memory link independent of decoding the transaction.

Abstract:

An improved liquid handling device used for transferring a selected quantity of liquid from one receptacle to another. The device includes a meniscus tracking feature which minimizes mixing in a liquid sample and contact between the sample and a sample-handling pipette during a liquid-transfer operation. Further included is a volume-correcting feature for improving the accuracy of volume withdrawn into or dispensed from the pipette during a liquid handling operation.
