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.

Abstract: An adapter card with compression-attached memory modules that can be inserted into a conventional vertical connector enables use of CAMMs in systems with vertical memory module connectors. In one example, an adapter card or riser card includes a printed circuit board (PCB) having an edge to be received by a dual-inline memory module (DIMM) connector. First conductive contacts proximate to the edge of the PCB are to be received by the DIMM connector, enabling the first conductive contacts to couple with contacts of the DIMM connector. Second conductive contacts on a face of the PCB are to couple with a first compression attached memory module (CAMM) via a first compression mount technology (CMT) connector. The adapter card includes conductive traces on or in the PCB between the first conductive contacts and the second conductive contacts to couple the CAMM with the DIMM connector.

Abstract: Methods and apparatus for differential I/O (input/output) cards using compression mount technology (CMT) connectors. Assemblies include a CMT connector having an array of spring-loaded pins or contacts that are configured to contact respective CMT contact pads on a pair of printed circuit board (PCBs), such as an add-in card (AIC) and a motherboard. Stacked assemblies are also disclosed including multiple CMT AIC or PCIe modules communicatively coupled using on module CMT connectors. The connector solutions may be used for AICs without changing the overall PCB form factor outline of existing AICs employing edge connectors. Under a stacked assembly of multiple CMT PCIe modules interconnected by on module CMT connectors, wiring in the PCBs is configured to provide signaling supporting multi-lane PCIe or CXL links for each CMT PCIe module. The CMT connector approach also is scalable and can support more pins/contacts to facilitate additional I/O bandwidth.
