    摘要: A NAND flash memory device is disclosed. The NAND flash memory device includes a NAND flash memory array defined as a plurality of sectors. Row decoding is performed in two levels. The first level is performed that is applicable to all of the sectors. This can be used to select a block, for example. The second level is performed for a particular sector, to select a page within a block in the particular sector, for example. Read and program operations take place to the resolution of a page within a sector, while erase operation takes place to the resolution of a block within a sector.

    摘要: A Multiple-bit per Cell (MBC) non-volatile memory apparatus, method, and system wherein a controller for writing/reading data to/from a memory array controls polarity of data by selectively inverting data words to maximize a number of bits to be programmed within (M−1) virtual pages and selectively inverts data words to minimize a number of bits to be programmed in an Mth virtual page where M is the number of bits per cell. A corresponding polarity control flag is set when a data word is inverted. Data is selectively inverted according the corresponding polarity flag when being read from the M virtual pages. A number of the highest threshold voltage programming states in reduced. This provides tighter distribution of programmed cell threshold voltage, reduced power consumption, reduced programming time, and enhanced device reliability.

    摘要: A flash memory device having at least two bank, where the each bank has an independently configurable page size and core controller. The core controller is local to each bank, and governs memory access operations for the bank that include read, program and erase operations. Each core controller controls timing and activation of row circuits, column circuits, voltage generators, and local input/output path circuits for a corresponding memory access operation of the bank. Concurrent operations are executable in multiple banks to improve performance. Each bank has a page size that is configurable with page size configuration data such that only selected wordlines are activated in response to address data. The configuration data can be loaded into the memory device upon power up for a static page configuration of the bank, or the configuration data can be received with each command to allow for dynamic page configuration of the bank.

    摘要: A dual function memory device architecture compatible with asynchronous operation and synchronous serial operation. The dual function memory device architecture includes one set of physical ports having two different functional assignments. Coupled between the physical ports and core circuits of the memory device are asynchronous and synchronous input and output signal paths or circuits. The signal paths include shared or dedicated buffers coupled to the ports, asynchronous and synchronous command decoders, a network of switches, and a mode detector. The mode detector determines the operating mode of the dual function memory device from a port, and provides the appropriate switch selection signal. The network of switches routes the input or output signals through the asynchronous or synchronous circuits in response to the switch selection signal. The appropriate command decoder interprets the input signals and provides common control logic with the necessary signals for initiating the corresponding operation.

A select voltage is applied through pass transistors to each of plural selected wordlines and an unselect voltage is applied through pass transistor to each of plural unselected wordlines of a selected block. A substrate voltage is applied to the substrate of the selected block. A common select voltage may be applied to each selected wordline and the common unselect voltage may be applied to each unselected wordline. Select and unselect voltages may be applied to any of the wordlines of a select block. A page erase verify operation may be applied to a block having plural erased pages and plural nonerased pages.
