    Abstract: A low power matchline sensing scheme where power is distributed according to the number of mismatching bits occurring on a matchline is disclosed. In particular, match decisions involving a larger number of mismatched bits consume less power compared to match decisions having a lesser number of mismatched bits. The low power matchline sensing scheme is based upon a precharge-to-miss sensing architecture, and includes a current control circuit coupled to each matchline of the content addressable memory array for monitoring the voltage level of the matchline during a search operation. The current control circuit provides a voltage control signal to the current source of the matchline to adjust the amount of current applied to the matchline in response to the voltage of the matchline. In otherwords, matchlines that are slow to reach the match threshold voltage due to the presence of one or more mismatching bits will receive less current than matchlines having no mismatching bits.

  • Publication number: 20070206412
    Abstract: A nonvolatile memory device improves the accuracy of screening testing while applying a voltage at or lower than the limit of the withstand voltage of an element for high voltage in the screening testing. The nonvolatile memory device includes a high voltage production circuit that produces a high voltage, a high voltage waveform conversion circuit to which the high voltage is input and which converts the voltage waveform, and a memory cell section provided with memory cells in which data rewriting is performed as a result of applying the converted high voltage. The high voltage waveform conversion circuit includes a test signal input section TEST and applies the high voltage input from the high voltage production circuit to the memory cell section without converting the voltage waveform when a test signal is input to the test signal input section.

  • Publication number: 20070206414
    Abstract: The method of fabricating a multi-bit flash memory cell begins with forming an ion implantation mask exposing a portion of a channel region in a semiconductor substrate. Ions are implanted into the exposed region thereby partially coding the threshold voltage to create one ion implanted channel region with a first threshold voltage, and a second region without implanted ions having a second threshold voltage. A tunnel dielectric layer is formed over the channel region and floating and control gates are formed over the tunnel dielectric layer.

  • Publication number: 20070206415
    Abstract: A non-volatile electrically erasable programmable read only memory (EEPROM) capable of storing two bit of information having a non-conducting charge trapping dielectric, such as silicon nitride, sandwiched between two silicon dioxide layers acting as electrical insulators is disclosed. The invention includes a method of programming, reading and erasing the two bit EEPROM device. The non-conducting dielectric layer functions as an electrical charge trapping medium. A conducting gate layer is placed over the upper silicon dioxide layer. A left and a right bit are stored in physically different areas of the charge trapping layer, near left and right regions of the memory cell, respectively. Each bit of the memory device is programmed in the conventional manner, using hot electron programming, by applying programming voltages to the gate and to either the left or the right region while the other region is grounded.

    Abstract: A nonvolatile semiconductor memory device having a plurality of electrically rewritable nonvolatile memory cells connected in aeries together is disclosed. A select gate translator is connected in series to the serial combination of memory cells. A certain one of the memory cells which is located adjacent to the select gate translator is for use as a dummy cell. This dummy cell is not used for data storage. During data erasing, the dummy cell is applied with the same bias voltage as that for the other memory cells.

  • Publication number: 20070206417
    Abstract: Methods and apparatus for decreasing oxide stress and increasing reliability of memory transistors are disclosed. Duration and frequency of exposure of memory transistor gates to read signals are significantly reduced. In some embodiments, after a short read cycle, the content of the memory cell is latched and maintained as long as the subsequent read attempts are directed to the same memory cell. In these embodiments the read cycle need only be long enough to latch the memory content of the cell, and as long as the subsequent read attempts target the same memory cell the latched value will be used instead of repeating the read process.

    Abstract: A single flash memory device has selectable read modes for either a segment mode or a page mode. The desired mode is selected by writing a control word to a mode control register. Selecting the segment mode causes the device to output selected memory segments. Selecting the page mode causes the device to output selected memory pages.

  • Publication number: 20070206421
    Abstract: Shifts in the apparent charge stored on a floating gate (or other charge storing element) of a non-volatile memory cell can occur because of the coupling of an electric field based on the charge stored in adjacent floating gates (or other adjacent charge storing elements). The problem occurs most pronouncedly between sets of adjacent memory cells that have been programmed at different times. To account for this coupling, the read process for a particular memory cell will provide compensation to an adjacent memory cell in order to reduce the coupling effect that the adjacent memory cell has on the particular memory cell.

    Abstract: Embodiments of NAND Flash memory devices and methods recognize that effective column coupling capacitance can be reduced by maintaining a sourced voltage on adjacent columns of an array. Maintaining the columns in a charged state prior to array operations (read, write, and program) reduces current surges and improves data read timing. Devices and methods charge the array columns at pre-charge and following array access operations.
