Abstract: A method of operation in an integrated circuit (IC) memory device is disclosed. The method includes refreshing a first group of storage rows in the IC memory device at a first refresh rate. A retention time for each of the rows is tested. The testing for a given row under test includes refreshing at a second refresh rate that is slower than the first refresh rate. The testing is interruptible based on an access request for data stored in the given row under test.

Abstract: Systems, among other embodiments, include topologies (data and/or control/address information) between an integrated circuit buffer device (that may be coupled to a master, such as a memory controller) and a plurality of integrated circuit memory devices. For example, data may be provided between the plurality of integrated circuit memory devices and the integrated circuit buffer device using separate segmented (or point-to-point link) signal paths in response to control/address information provided from the integrated circuit buffer device to the plurality of integrated circuit buffer devices using a single fly-by (or bus) signal path. An integrated circuit buffer device enables configurable effective memory organization of the plurality of integrated circuit memory devices. The memory organization represented by the integrated circuit buffer device to a memory controller may be different than the actual memory organization behind or coupled to the integrated circuit buffer device.

Abstract: Beds may include environmental control components, which may be temperature control components and pressure adjustment components in some embodiments. The environmental control components may be configured, for example by a controller, to provide different sleep environments based on identity of sleepers using or expected to use the bed. The controller may receive information as to how to configure the components based on one or more sleep profiles for sleepers expected to use the bed. The sleep profiles may be received from a server, or received from a smartphone of a sleeper. The sleep profiles may be deleted from the bed after use.

Abstract: The embodiments described herein describe technologies of dynamic random access memory (DRAM) components for high-performance, high-capacity registered memory modules, such as registered dual in-line memory modules (RDIMMs). One DRAM component may include a set of memory cells and steering logic. The steering logic may include a first data interface and a second data interface. The first and second data interfaces are selectively coupled to a controller component in a first mode and the first data interface is selectively coupled to the controller component in a second mode and the second data interface is selectively coupled to a second DRAM component in the second mode.

Abstract: The embodiments described herein describe technologies for non-volatile memory persistence in a multi-tiered memory system including two or more memory technologies for volatile memory and non-volatile memory.

Abstract: An integrated circuit includes a delay circuit and first and second interface circuits. The delay circuit delays a first timing signal by an internal delay to generate an internal timing signal. The first interface circuit communicates data to an external device in response to the internal timing signal. The second interface circuit transmits an external timing signal for capturing the data in the external device. An external delay is added to the external timing signal in the external device to generate a delayed external timing signal. The delay circuit sets the internal delay based on a comparison between the delayed external timing signal and a calibration signal transmitted by the first interface circuit.

Abstract: A memory module is disclosed that includes a substrate, a memory device that outputs read data, and a buffer. The buffer has a primary interface for transferring the read data to a memory controller and a secondary interface coupled to the memory device to receive the read data. The buffer includes error logic to identify an error in the received read data and to identify a storage cell location in the memory device associated with the error. Repair logic maps a replacement storage element as a substitute storage element for the storage cell location associated with the error.

Abstract: A bed integrates sensors and other inputs to detect specific sleep environment conditions including point-specific pressure and/or temperature conditions. The bed includes a controller for commanding actuator or other devices to adjust these conditions. The controller may do so based on reference patterns for conditions and profiles of desired conditions. Information regarding the conditions may be provided to a remote computer, which may analyze the conditions and provide revised profiles of desired conditions.

Abstract: Memory modules, systems, memory controllers and associated methods are disclosed. In one embodiment, a memory module includes a module substrate having first and second memory devices. Buffer circuitry disposed on the substrate couples to the first and second memory devices via respective first and second secondary interfaces. The buffer circuitry includes a primary signaling interface for coupling to a group of signaling links associated with a memory controller. The primary signaling interface operates at a primary signaling rate and the first and second secondary data interfaces operate at a secondary signaling rate. During a first mode of operation, the primary interface signaling rate is at least twice the secondary signaling rate. A first time interval associated with a transfer of first column data via the first secondary interface temporally overlaps a second time interval involving second column data transferred via the second secondary interface.
