    摘要: The effects of bit line-to-bit line coupling in a non-volatile memory are addressed. An inhibit voltage is applied on a bit line of a storage element to be programmed to inhibit programming during a portion of a program voltage. The inhibit voltage is subsequently removed during the program voltage to allow programming to occur. Due to the proximity of bit lines, the change in the bit line voltage is coupled to a neighboring unselected bit line, reducing the neighboring bit line voltage to a level which might be sufficient to open a select gate and discharge a boost voltage. To prevent this, the select gate voltage is temporarily adjusted during the change in the bit line voltage to ensure that the biasing of the select gate on the unselected bit line is not sufficient to open the select gate.

    摘要: The process for programming a set of memory cells is improved by adapting the programming process based on behavior of the memory cells. For example, a set of program pulses is applied to the word line for a set of flash memory cells. A determination is made as to which memory cells are easier to program and which memory cells are harder to program. Bit line voltages (or other parameters) can be adjusted based on the determination of which memory cells are easier to program and which memory cells are harder to program. The programming process will then continue with the adjusted bit line voltages (or other parameters).

    摘要: A non-volatile semiconductor memory system (or other type of memory system) is programmed in a manner that avoids program disturb. In one embodiment that includes a flash memory system using a NAND architecture, program disturb is avoided by increasing the channel potential of the source side of the NAND string during the programming process. One exemplar implementation includes applying a voltage (e.g. Vdd) to the source contact and turning on the source side select transistor for the NAND sting corresponding to the cell being inhibited. Another implementation includes applying a pre-charging voltage to the unselected word lines of the NAND string corresponding to the cell being inhibited prior to applying the program voltage.

    摘要: In a non-volatile semiconductor memory system (or other type of memory system), a memory cell is programmed by changing the threshold voltage of that memory cell. Because of variations in the programming speeds of different memory cells in the system, the possibility exists that some memory cells will be over programmed. That is, in one example, the threshold voltage will be moved past the intended value or range of values. The present invention includes determining whether the memory cells are over programmed.
