    摘要: A non-volatile memory device capable of reading and writing a large number of memory cells with multiple read/write circuits in parallel has features to reduce power consumption during read, and program/verify operations. A read or program verify operation includes one or more sensing cycles relative to one or more demarcation threshold voltages to determine a memory state. In one aspect, selective memory cells among the group being sensed in parallel have their conduction currents turned off when they are determined to be in a state not relevant to the current sensing cycle. In another aspect, a power-consuming period is minimized by preemptively starting any operations that would prolong the period. In a program/verify operation cells not to be programmed have their bit lines charged up in the program phase. Power is saved when a set of these bit lines avoids re-charging at every passing of a program phase.

    摘要: A method, system and apparatus for voice enabling a user preference interface in a multimodal content browser. A method for voice enabling a user preference interface in a multimodal content browser can include matching voice input to a bound command in a speech grammar and invoking logic in the user preference interface consistent with the bound command in the speech grammar. The matching step can include comparing voice input to entries in a markup language specified speech grammar and locating the bound command in the specified speech grammar based upon the comparison. In this regard, the method further can include identifying a variable in the bound command, looking up the variable in a table, retrieving a corresponding parameter for the variable from the table, and replacing the variable with the corresponding parameter in the bound command.

    摘要: The present invention presents techniques whereby a memory system interrupts a programming process and restarts it including additional data. More specifically, when a memory system programs data into a group of cells together as programming unit, programming can begin with less than the full data content which the group can hold. In one embodiment, the present invention allows overlapped programming of upper and lower data pages, where once the memory begins programming the lower logical data page, if data is received for the upper page assigned to the same physical page, programming is interrupted and recommenced with the concurrent programming of both the upper and the loser pages. In a complimentary embodiment, when a page contains multiple sectors of data, programming of the physical page can begin when one or more, but less than all, of the sectors forming the corresponding logical page have been received, stopped and restarted to include additional sectors of the page.

    摘要: Techniques of reducing erroneous readings of the apparent charge levels stored in a number of rows of memory cells on account of capacitive coupling between the cells. All pages of a first row are programmed with a first pass, followed by programming all pages of a second adjacent row with a first pass, after which the first row is programmed with a second pass, and then all pages of a third row are programmed with a first pass, followed by returning to program the second row with a second pass, and so on, in a back-and-forth manner across the rows of an array. This minimizes the effect on the apparent charge stored on rows of memory cells that can occur by later writing data into adjacent rows of memory cells.

    摘要: Source line bias is an error introduced by a non-zero resistance in the ground loop of the read/write circuits. During sensing the control gate voltage of a memory cell is erroneously biased by a voltage drop across the resistance. This error is minimized when the current flowing though the ground loop is reduced. A method for reducing source line bias is accomplished by read/write circuits with features and techniques for multi-pass sensing. When a page of memory cells are being sensed in parallel, each pass helps to identify and shut down the memory cells with conduction current higher than a given demarcation current value. In particular, the identified memory cells are shut down after all sensing in the current pass have been completed. In this way the shutting down operation does not disturb the sensing operation. Sensing in subsequent passes will be less affected by source line bias since the total amount of current flow is significantly reduced by eliminating contributions from the higher current cells. In another aspect of sensing improvement, a reference sense amplifier is employed to control multiple sense amplifiers to reduce their dependence on power supply and environmental variations.

    摘要: A memory device and a method thereof allow programming and sensing a plurality of memory cells in parallel in order to minimize errors caused by coupling from fields of neighboring cells and to improve performance. The memory device and method have the plurality of memory cells linked by the same word line and a read/write circuit is coupled to each memory cells in a contiguous manner. Thus, a memory cell and its neighbors are programmed together and the field environment for each memory cell relative to its neighbors during programming and subsequent reading is less varying. This improves performance and reduces errors caused by coupling from fields of neighboring cells, as compared to conventional architectures and methods in which cells on even columns are programmed independently of cells in odd columns.
