摘要： Data scrambling techniques implemented externally to a flash memory device are disclosed which can be used in concert with flash memory on-chip copy functionality operating internally to the flash device, thus supporting high performance copying operations. All the data stored in the flash may be scrambled, including headers and control structures. Robust file system operation may be achieved, including the capability to tolerate a power loss at any time, and yet be able to relocate data internally within the flash without having to de-scramble and then re-scramble the data. An exemplary hardware based solution has little or no impact on overall system performance, and may be implemented at very low incremental cost to increase overall system reliability. The data scrambling technique preferably uses a logical address, such as logical block address or logical page address, rather than a physical address, to determine a seed scrambling key.

摘要： In order to maintain a memory system's performance levels to its end-of-life, latency threshold level(s) are specified and associated with different memory system operating parameters. In one embodiment, the memory system monitors and gathers performance statistics in real time, and in accordance with specific memory transfer sizes. A current latency level can be dynamically calculated using the performance statistics and compared to previously established latency threshold levels. If the current latency level is greater than or equal to a specific latency threshold level, the memory system's configuration setting can be adjusted according to the operating parameters associated with the latency threshold level to offset the increased latency.

摘要： A method and system for phasing power-intensive operations is disclosed. A non-volatile storage device controller detects a power reset. The controller is in communication with non-volatile memories in the non-volatile storage device. In response to detecting a power reset, the controller determines a current consumption necessary to reset the non-volatile memories in the non-volatile storage device. The controller simultaneously resets all of the non-volatile memories when the determined current consumption is less than a current consumption threshold. If the determined current consumption is greater than the current consumption threshold, the controller resets a first subset of the plurality of non-volatile memories, and after a predetermined delay, resets a second subset of the non-volatile memories. Therefore, a power-intensive operation may be performed without exceeding a current consumption threshold by dividing the operation into a sequence of steps that do not exceed the threshold.

摘要： A nonvolatile memory array includes two or more devices, each device containing data that is scrambled using a different scrambling scheme. When the same data is provided and stored in both devices, different data patterns occur in each device, so that if one of the patterns causes data pattern induced errors, the original data can be recreated from another copy that does not share the same data pattern.

摘要： An optical distribution architecture is disclosed wherein wavelength stabilized continuous wavelength lasers are centrally positioned in tandem with star couplers to distributed laser power among a plurality of lightguide paths. The laser power apportioned to each such path may then be locally or remotely modulated thereby reducing the number of lasers required to equip a network. Advantageously, lightguide fibres are single mode and polarization maintaining.

摘要： A method and apparatus for reducing power consumption during an operation in a non-volatile storage device is disclosed. A non-volatile storage device controller that is in communication with a non-volatile memory in the non-volatile storage device receives a characteristic corresponding to a time duration required for the non-volatile memory to complete an operation. The controller disables a circuit that indicates when an operation by the non-volatile memory is complete. The controller then initiates the operation in the non-volatile memory, and maintains the circuit in a disabled state for a first predetermined time that is a portion of the time duration. The controller enables the circuit upon expiration of the first predetermined time and prior to the completion of the operation. The controller receives an indication of the completion of the operation via the circuit.
