    摘要: A method and system have been described for counteracting and correcting for read disturb effects in blocks of flash memory. The method may include the step of a controller of the memory system performing a read scrub scan on only a portion of one targeted word line in a block at desired intervals. The controller may calculate whether a read scrub scan is necessary based on a probabilistic determination that is calculated in response to each received host read command. The controller may then place a block associated with the targeted word line into a refresh queue if a number of errors are detected in the targeted word line that meets or exceeds a predetermined threshold. The block refresh process may include copying the data from the block into a new block during a background operation.

    摘要: A solution is provided for automatically adjusting a webpage. According to the method of the present invention it can be automatically learned what the user's historical browsing behaviors are and thereby predict which block in the webpage would interest the user more so that it would be the one to be browsed and then adjust display of the block accordingly. Thus, with the present invention, limited screen resources can be utilized to more efficiently display the content that would interest a user when the user browses a webpage. A system for automatically adjusting a webpage and a computer readable article of manufacture tangibly embodying non-transitory computer readable instructions which, when executed, cause a computer to carry out the steps of a method for automatically adjusting a webpage, are also provided.

    摘要: A two-phase critical interleave PFC boost converter, includes a master-side control circuit configured to critically control a first switching element based on a master signal; and a slave-side control circuit configured to critically control a second switching element based on a slave-signal with a phase difference of 180° from the master signal. In the PFC boost converter, an off period generator of the master-side control circuit feeds an M_ON signal which is the same in waveform as the master signal to an on phase controller of the slave-side control circuit, and the slave-side control circuit determines the rising timing of the slave signal from the rising time of the master signal.

    摘要: Non-volatile storage devices and techniques for operating non-volatile storage are described herein. One embodiment includes accessing “n” pages of data to be programmed into a group of non-volatile storage elements. The “n” pages are mapped to a data state for each of the non-volatile storage elements based on a coding scheme that evenly distributes read errors across the “n” pages of data. Each of the non-volatile storage elements in the group are programmed to a threshold voltage range based on the data states to which the plurality of pages have been mapped. The programming may include programming the “n” pages simultaneously. In one embodiment, mapping the plurality of pages is based on a coding scheme that distributes a significant failure mode (for example, program disturb errors) to a first of the pages and a significant failure mode (for example, data retention errors) to a second of the pages.

    摘要: Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. Input data is written and staged in the first portion before being copied to the second portion. An error management provides checking the quality of the copied data for excessive error bits. The copying and checking are repeated on a different location in the second portion until either a predetermined quality is satisfied or the number or repeats exceeds a predetermined limit. The error management is not started when a memory is new with little or no errors, but started after the memory has aged to a predetermined amount as determined by the number of erase/program cycling its has experienced.
