  • Publication number: 20240364037
    Abstract: Compression Attached Memory Module (CAMM) connector pin with multi-spring (dual bend direction) levers and associated connectors. The connector pin comprises an upper cantilevered spring member coupled to an upper portion of a body and a lower cantilevered spring member coupled to a lower portion of the body. Each of the upper and lower cantilevered spring members include at least one forward bending lever and a backward bending lever. The upper cantilevered spring member may have a pair of arms merging to form an upper unified spring member having a nose and looping backwards over the arms and having an apex. A lower cantilevered spring may have a pair of legs merging to form a lower unified spring member having a nose and looping backwards under the legs and having a bottom. When compressed the forward and backward bending levers counteract one another in the horizontal plane, reducing horizontal displacement.

  • Publication number: 20240028531
    Abstract: A memory subsystem triggers dynamic switching for memory devices to provide access to active memory devices and prevent access to inactive memory devices. Dynamic switching enables a single bus to switch between multiple memory devices whose capacity otherwise exceeds the capacity of the single bus. A switch can be mounted in a memory module or directly on a motherboard alongside the memory devices. A memory controller can toggle a chip select signal as a single control signal to drive the switch. Each switch includes pairs of field effect transistors (FETs), including any of CMOS, NMOS and PMOS FETs. The switch electrically isolates inactive memory devices to prevent access without the need to electrically short the devices.

  • Publication number: 20230030274
    Abstract: Methods and apparatus relating to a resistive network splitter for enhanced probing solutions are described. In one embodiment, an interposer interface is coupled between a first component and a second component to allow a probe to capture one or more waveforms to be exchanged between the first component and the second component. A resistive network splitter couples the interposer interface to the probe and the second component and the resistive network comprises a plurality of resistors. Other embodiments are also claimed and disclosed.

  • Publication number: 20210376448
    Abstract: In one embodiment, an apparatus includes first and second via structures in a substrate. Each via structure defines a coupling element that extends from the via structure toward the other via structure such that the coupling elements capacitively couple with one another in an area between the first and second via structures.

  • Publication number: 20180189214
    Abstract: Devices include a connecting card that may be used in a memory connector. The connecting card may include a substrate including a first substrate region and a second substrate region, a plurality of adjacent signal pathways extending from the first substrate region to the second substrate region, and a capacitor positioned between each of the adjacent signal pathways. Other embodiments are described and claimed.
