摘要:
A mass storage device that utilizes one or more solid-state memory components to store data for a host system, and a method for increasing the write endurance of the memory components. The memory components are periodically heated above an intrinsic operating temperature thereof to a preselected temperature that is sufficient to thermally recondition the memory component in a manner that increases the write endurance of the memory component.
摘要:
A solid-state mass storage device and method of anticipating a failure of the mass storage device resulting from a memory device of the mass storage device reaching a write endurance limit. A procedure is then initiated to back up data to a second mass storage device prior to failure. The method includes assigning at least a first memory block of the memory device as a wear indicator, using other memory blocks of the memory device as data blocks for data storage, performing program/erase (P/E) cycles and wear leveling on the data blocks, subjecting the wear indicator to more P/E cycles than the data blocks, performing integrity checks and monitoring the bit error rate of the wear indicator, and taking corrective action if the bit error rate increases, including the initiation of the backup procedure and generating a request to replace the device.

A modular mass storage system and method that enables cableless mounting of ATA and/or similar high speed interface-based mass storage devices in a computer system. The system includes a printed circuit board, a system expansion slot interface on the printed circuit board and comprising power and data pins, a host bus controller on the printed circuit board and electrically connected to the system expansion slot interface, docking connectors connected with the host bus controller to receive power and exchange data therewith and adapted to electrically couple with industry-standard non-volatile memory devices without cabling therebetween, and features on the printed circuit board for securing the memory devices thereto once coupled to the docking connectors.
摘要:
A biosignal-computer-interface apparatus and method. The apparatus includes one or more devices for generating biosignals based on at least one physiological parameter of an individual, and a computer-interface device capable of performing multiple tasks, including converting the biosignals into at least one input signal, establishing a scale encompassing different levels of the input signal, multiplying the input signal into parallel control channels, dividing the scale into multiple zones for each of the parallel control channels, assigning computer commands to each individual zone of the multiple zones, and generating the computer command assigned to at least one of the individual zones if the level of the input signal is within the at least one individual zone. The individual zones can be the same or different among the parallel control channels.
摘要:
A solid state memory-based mass storage device and a method of transferring data between a memory controller and at least one memory device of the mass storage device through optical input/output links that transmit multiplexed optical data signals between the memory device and controller.
摘要:
A system (10) and method for monitoring power consumption of a computer system component, such as a central processing unit (CPU), of a desktop computer system. The component is supplied with supply power from a power supply unit (22) of the computer through a power supply cable (14). A coupling (12) is disposed between the power supply unit (22) and a substrate (e.g., motherboard) on which the component is mounted, and is electrically connected to at least one power supply line (18) of the power supply cable (14) and a power supply connector (24) on the substrate (20). The power supply line (18) carries a supply voltage, and one or more devices (26,34,36,46) associated with the coupling (12) determine current flow through the power supply line (18) and provide a power consumption reading for the component based on the supply voltage and the current flow through the power supply line (18).
摘要:
A solid-state mass storage device and method of operating the storage device to anticipate the failure of at least one memory device thereof before a write endurance limitation is reached. The method includes assigning at least a first memory block of the memory device as a wear indicator that is excluded from use as data storage, using pages of at least a set of memory blocks of the memory device for data storage, writing data to and erasing data from each memory block of the set in program/erase (P/E) cycles, performing wear leveling on the set of memory blocks, subjecting the wear indicator to more P/E cycles than the set of memory blocks, performing integrity checks of the wear indicator and monitoring its bit error rate, and taking corrective action if the bit error rate increases.
摘要:
A mass storage device and method that utilize storage memory and a shadow memory capable of increasing the speed associated with copying data from one location to another location within the storage memory without the need to access a host computer for the copy transaction. A controller of the mass storage device receives a file copy request for a file to be copied between first and second locations within the storage memory. Data from the first location within the storage memory is then loaded into a shadow memory means of the mass storage device, and then the data is written from the shadow memory means to the second location within the storage memory.

摘要:
A nonvolatile storage device adapted for use with computers, workstations and other processing apparatuses. The storage device includes a printed circuit board, a nonvolatile memory array comprising at least two sub-arrays that contain nonvolatile solid-state memory devices, and control circuitry for interfacing with the processing apparatus. The control circuitry includes an abstraction layer and at least two memory control units configured to communicate data, address and control signals with the sub-arrays of the memory devices. A bus connects each memory control unit to a corresponding one of the sub-arrays. The control circuitry further includes a crossbar switch that functionally connects each memory control unit to the abstraction layer. The storage device is capable of overcoming limitations of current SSD designs by enabling independent read and write transfers (accesses) to the memory devices of the storage device, including concurrent read and write accesses.
