  • Patent number: 7111211
    Abstract: Two heat chambers are placed side-by-side. Heated air is blown upward through a first chamber and downward through a second heat chamber. An upper heating unit has a blower and heater that heat air exiting the first chamber and blows the heated air into the top of the second chamber. A lower heating unit has a blower and heater that heat air exiting the second chamber and blows the heated air into the top of the first chamber. Air is circulated in a loop through the two heat chambers by the two heating units. Inefficiencies from return pipes are eliminated by using the second chamber. The heated air is blown past memory modules under test in a heat chamber that has an insulated backplane. Pattern-generator cards outside the heat chamber exercise the memory modules and are cooled while memory modules in the heat chamber are heated.

  • Publication number: 20060203556
    Abstract: A Flash memory controller is disclosed. The Flash memory controller comprises a host interface, a Flash memory interface, controller logic coupled between the host interface, the controller logic handling a plurality of voltages. The controller also includes a mechanism for allowing a multiple voltage host to interface with a high voltage or a multiple voltage Flash memory. A multiple voltage Flash memory controller in accordance with the present invention provides the following advantages over conventional Flash memory controllers: (1) a voltage host is allowed to interface with multiple Flash memory components that operate at different voltages in any combination; (2) power consumption efficiency is improved by integrating the programmable voltage regulator, and voltage comparator mechanism with the Flash memory controller; (3) External jumper selection is eliminated for power source configuration; and (4) Flash memory controller power source interface pin-outs are simplified.

  • Publication number: 20060138221
    Abstract: A computer readable medium including executable instructions to analyze radio frequency (RF) tag information includes executable instruction to access cross-enterprise RF tag information, identify a product transition based upon the cross-enterprise RF tag information, and define a new product path based upon the product transition, where the new product path defines product pedigree information. Additional executable instructions authenticate a user, secure product information, supply product pedigree information corresponding to the product information, and verify the pedigree of the product based upon the product pedigree information.

  • Publication number: 20060005856
    Abstract: Embodiments of the present invention provide a method of reducing damage to the substrate support by the cleaning gas during a cleaning process of the processing chamber, such as by reducing aluminum fluoride formation on the substrate support. In one embodiment, a method of cleaning a semiconductor process chamber which is used for processing a substrate disposed on a surface of a substrate support comprises introducing a cleaning gas into a process chamber through an inlet facing a surface of a substrate support. The inlet is spaced from the surface of the substrate support by a clean spacing. Reactive species are provided from the cleaning gas to clean the process chamber. The clean spacing is substantially greater than a process spacing between the inlet and the surface of the substrate support during processing of a substrate on the substrate support in the process chamber.

  • Patent number: 6981886
    Abstract: A levered handle has an elongated slot that allows the levered handle to both slide and pivot over a pivot axis. The levered handle is slid over the pivot axis to allow a notch engager to engage a notch on a memory module. Then the notch engager is forced downward as the levered handle pivots upward about the pivot axis, causing a downward force to be applied to the notch on the memory module. This forces the memory module into a memory module socket. The memory module socket requires a reduced insertion force because the notch engager on the levered handle engages the notch on the memory module and applies downward pressure. A levered handle without the elongated slot can slide along the pivot axis perpendicular to the memory module to engage the notch. Both ejection and insertion forces can be reduced.

  • Publication number: 20050246594
    Abstract: Memory modules with an extra dynamic-random-access memory (DRAM) chip for storing error-correction code (ECC) are tested on a personal computer (PC) motherboard tester using a cross-over extender card inserted into a memory module socket on the motherboard. ECC code generated on the motherboard is normally stored in the extra ECC DRAM chip, preventing test patterns such as checkerboards and walking-ones to be written directly to the ECC DRAM chip. During testing, the cross-over extender card routes signals from the motherboard for one of the data DRAM chips to the ECC DRAM chip, while the ECC code is routed to one of the data DRAM chips. The checkerboard or other test pattern is thus written and read from the ECC DRAM chip that normally stores the ECC code. The cross-over extender card can be hardwired, or can have a switch to allow normal operation or testing of the ECC DRAM chip.

  • Publication number: 20050125712
    Abstract: Hot air blown past memory modules under test in a heat chamber is improved. Hot air entering the chamber from an inlet pipe is split by a manifold and deflectors. Holes in the manifold allow for a relatively even air distribution within the chamber, minimizing temperature variations. Return air is collected by a heat-chamber bottom cover into a return pipe. A heating unit re-heats the return air and blows it into the inlet pipe. One side of the heat chamber is an insulated backplane. Memory modules are inserted into sockets on module motherboards, which are inserted into motherboard sockets on the backplane. On the other side of the backplane, card sockets receive pattern-generator cards outside the heat chamber but electrically connected to the module motherboards through the backplane. The pattern-generator cards exercise the memory modules. The pattern-generator cards are cooled while memory modules in the heat chamber are heated.

  • Patent number: 6824410
    Abstract: A test socket for testing memory modules requires little or no insertion force. A base holds a funnel-shaped guide that guides the edge of the memory module into a desired position. Two housing halves are connected to the base by one or more hinges. The housing halves pivot around the hinges to open and close the test socket. Linkages, springs, or solenoids move the housing halves. Metal contact pads on flexible membranes are attached to each housing half and clamp onto contact pads on an inserted memory module when the housing halves are closed. Scooped vise clamps can be used to pinch together the ends of the housing halves to close the test socket. More test sockets can be fitted into a smaller pitch using the scooped vise clamps since the solenoids are along the longer axis of the test socket.
