摘要： Methods and devices for operating non-volatile storage are disclosed. One or more programming conditions depend on the location of the word line that is selected for programming, which may reduce or eliminate program disturb. The voltage applied to the gate of a select transistor of a NAND string may depend on the location of the selected word line. This could be either a source side or drain side select transistor. This may prevent or reduce program disturb that could result due to DIBL. This may also prevent or reduce program disturb that could result due to GIDL. A negative bias may be applied to the gate of a source side select transistor when programming at least some of the word lines. In one embodiment, progressively lower voltages are used for the gate of the drain side select transistor when programming progressively higher word lines.

摘要： Methods and devices for operating non-volatile storage are disclosed. One or more programming conditions depend on the location of the word line that is selected for programming. Applying a selected word line dependent program condition may reduce or eliminate program disturb. The voltage applied to a common source line may depend on the location of the word line that is selected for programming. This may prevent or reduce punch-through conduction, which may prevent or reduce program disturb. The voltage applied to bit lines of unselected NAND strings may depend on the location of the word line that is selected for programming. This may prevent or reduce punch-through conduction.

摘要： Channel boosting is improved in non-volatile storage to reduce program disturb. A pre-charge module voltage source is used to pre-charge bit lines during a programming operation. The pre-charge module voltage source is coupled to a substrate channel via the bit lines to boost the channel. An additional source of boosting is provided by electromagnetically coupling a voltage from a conductive element to the bit lines and the channel. To achieve this, the bit lines and the channel are allowed to float together by disconnecting the bit lines from the voltage sources. The conductive element can be a source line, power supply line or substrate body, for instance, which receives an increasing voltage during the pre-charging and is proximate to the bit lines.

摘要： Stacked gate structures for a NAND string are created on a substrate. Source implantations are performed at a first implantation angle to areas between the stacked gate structures. Drain implantations are performed at a second implantation angle to areas between the stacked gate structures. The drain implantations create lower doped regions of a first conductivity type in the substrate on drain sides of the stacked gate structures. The source implantations create higher doped regions of the first conductivity type in the substrate on source sides of the stacked gate structures.

摘要： Data is programmed into and read from a set of target memory cells. When reading the data, temperature compensation is provided. The temperature compensation is based on temperature information and the state of one or more neighbor memory cells. In one embodiment, when data is read from set of target memory cells, the system senses the current temperature and determines the differences in temperature between the current temperature and the temperature at the time the data was programmed. If the difference in temperature is greater than a threshold, then the process of reading the data includes providing temperature compensation based on temperature information and neighbor state information. In one alternative, the decision to provide the temperature compensation can be triggered by conditions other than a temperature differential.

摘要： A method for creating NAND flash memory. Source implantations are performed at a first implantation angle to areas between stacked gate structures of a NAND string. Drain implantations are performed at a second implantation angle to areas between the stacked gate structures. The implantations can dope a source line area while not doping a bit line contact area, and providing an additional implantation for the bit line contact area, or dope the bit line contact area while not doping the source line area, followed by an additional implantation for the source line area, or dope neither the source line area nor the bit line contact area, followed by additional implantations for the source line area and the bit line contact area.
