A physiological data collection device obtains physiological data from a subject interface on a subject. The physiological data collection device includes a data connector such as a USB connector for connecting directly to a computer. When the physiological data collection device is connected to the computer, the physiological data is uploaded to a remote data processing center for computer-based analysis and review by a medical professional. A report can be provided to the subject based on the analysis and review. When the subject interface is physically connected to the physiological data collection device, the data connector is prevented from being connected to an external device such as the computer.

A storage array uses paged metadata. Each storage director has access to a plurality of object storage systems which describe locations of paged metadata in backing storage. Each object storage system includes different types of inodes which describe objects in backing storage. The object storage systems are used to locate and relocate metadata for loading into global memory, and creation and deletion of objects. An object storage system may be selected based on factors including ratio of different inode types, locality of object usage and anticipated object activity level.

A host device is configured to read and write information from and into a card and to supply a supply voltage that belongs to a first voltage range or a second voltage range which is lower than the first voltage range, and issues a voltage identification command to the card. The voltage identification command includes a voltage range identification section, an error detection section, and a check pattern section. The voltage range identification section includes information indicating which one of the first voltage range and the second voltage range the supply voltage belongs. The error detection section has a pattern configured to enable the card which has received the voltage identification command to detect errors in the voltage identification command. The check pattern section has a preset pattern.

A memory module comprises a volatile memory subsystem, a non-volatile memory subsystem, and a module control device. The module control device is configured to read data from the non-volatile memory subsystem in response to a set of signals received from the memory channel indicating a non-volatile memory access request to transfer the data from the non-volatile memory subsystem to the volatile memory subsystem, and to provide at least a portion of the data to the volatile memory subsystem in response to receiving a dummy write memory command including a memory address related to the non-volatile memory access request via the memory channel. The volatile memory subsystem is further configured to receive the dummy write memory command and to receive the at least a portion of the first data in response to the dummy write memory command.

A proxy device that may query other devices for their configurations is disclosed. The proxy device may include a device communication logic to communicate with the devices over a control plane. The proxy device may also include reception logic that may receive a query from a host. The query may request information from the proxy device about the configurations of the devices. The proxy device may also include a transmission logic to send the device configurations to the host.

A memory card is attached to a host device, and includes a data control circuit which transfers data with respect to the host device in synchronism with a rise edge and a fall edge of a clock signal.

A one-time programmable memory device is provided in the invention. The one-time programmable memory device includes a one-time programmable memory and a memory controller. The one-time programmable memory includes a first block and a second block. The first block includes a plurality of initial address units and each initial address unit corresponds to a variable to record the storage address of its corresponding variable, and wherein the second block includes a plurality of storage units and each storage unit has a corresponding storage address. The memory controller is coupled to the one-time programmable memory. The memory controller allocates the storage address to the variable. The content of each variable is stored in the storage unit corresponding to the storage address corresponding to the variable. The number of initial address units is smaller than the number of storage units.

A memory card is attached to a host device, and includes a data control circuit which transfers data with respect to the host device in synchronism with a rise edge and a fall edge of a clock signal.

A hybrid memory system provides rapid, persistent byte-addressable and block-addressable memory access to a host computer system by providing direct access to a both a volatile byte-addressable memory and a volatile block-addressable memory via the same parallel memory interface. The hybrid memory system also has at least a non-volatile block-addressable memory that allows the system to persist data even through a power-loss state. The hybrid memory system can copy and move data between any of the memories using local memory controllers to free up host system resources for other tasks.
