Abstract: Reducing peak current and/or power consumption during verify of a non-volatile memory is disclosed. During a program verify, only memory cells in a first physical segment of the selected word line are verified during an initial program loop; memory cells in a different physical segment of the word line are locked out and not verified. The locked out memory cells may be slower to program. During a later program loop, memory cells in all physical segments are program verified. Locked out strings do not conduct a significant current during verify, thus reducing current/power consumption.

Abstract: Improving endurance for non-volatile memory by dynamic erase depth is disclosed. A group of memory cells are erased. Then, at least some of the erased memory cells are programmed. Programming the memory cells typically impacts the erase threshold distribution of those memory cells that were intended to stay erased. The erase depth of the next erase can be adjusted based on how the program operation affects the erase threshold distribution. As one example, the upper tail of the erase distribution is measured after programming. The higher the upper tail, the shallower the next erase, in one embodiment. This helps to improve endurance. In one embodiment, the erase depth is adjusted by determining a suitable erase verify level. Rather than (or in addition to) adjusting the erase verify level, the number of erase pulses that are performed after erase verify passes can be adjusted to adjust the erase depth.

Abstract: An X-ray imaging method including the following steps is provided. An X-ray source is provided, wherein the X-ray source includes a housing, a cathode, and an anode target. The housing has an end window. The cathode is disposed in the housing, and the anode target is disposed beside the end window. The cathode is caused to provide an electron beam. A portion of the electron beam hits at least a part of areas of the anode target to generate an X-ray and the X-ray is emitted out of the housing through the end window. The X-ray is caused to irradiate an object to generate X-ray image information. An image detector is used to receive the X-ray image information. Besides, an X-ray source is also provided.

Abstract: A method and non-volatile storage system are provided in which the voltage applied to the source end of a NAND string depends on the location of the non-volatile storage element that is selected for sensing. This may be done without body-biasing the NAND string. Having the magnitude of the voltage applied to the source end of a NAND string depend on the location of the selected memory cell (without any body biasing) helps to mitigate failures that are dependent on which word line is selected during a sensing operation of one embodiment. Additionally, the magnitude of a read pass voltage may depend on either the source line voltage or the location of the selected memory cell.

Abstract: Methods and devices for charging unselected bit lines are disclosed. The rate at which inhibited (or unselected) bit lines are charged may depend on a program condition. The program condition may be completion of a program loop. As another example, the program condition may be a certain program state completing or nearly completing programming. As one example, the bit lines may be charged at a faster rate prior to the program condition occurring than after the program condition. As another example, the bit lines may be charged at a slower rate prior to the program condition than after the program condition. Charging the unselected bit lines at a slower rate may reduce current consumption. Charging the unselected bit lines at a faster rate may allow for faster programming.

Abstract: A method of making a floor panel includes the steps of: providing an adhesive on a release member; laminating or marrying the release member to a bottom layer such that the adhesive is between the release member and the bottom layer; removing a portion of the release member to expose an area of the adhesive; and adhering a top layer to the area such that the top layer is offset with respect to the bottom layer in a direction of length and width and a marginal end portion of a top surface of the bottom layer and a marginal end portion of the bottom surface of the top layer is exposed.

Abstract: A set of memory cells can be erased by individually erasing portions of the set in order to normalize the erase behavior of each memory cell and provide more consistent erase rates. An erase voltage pulse can be applied to the set of memory cells with a first group of cells biased for erase and a second group biased to inhibit erase. The erase depth is made shallower as the device is cycled more.

Abstract: A system for reducing read disturb on edge word lines in non-volatile storage is disclosed. In one embodiment, the memory cells on edge word lines are programmed using a series of pulses that have an initial magnitude and step size between pulses that are lower than for memory cells on word lines that are not edge word lines. Additionally, when reading memory cells on word lines that are not edge word lines, the edge word lines receive a lower pass voltage than the default pass voltage applied to other unselected word lines. In another embodiment. the system applies a higher than normal bias on a neighboring word lines when reading memory cells on an edge word line.

Abstract: 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.

At least one of the marginal end portions has an adhesive. The floor panels are stacked in the box in pairs. Each of the pairs is stacked such that the top surfaces of the top layers of each of the pairs of the floor panels are facing each other.

Abstract: In a non-volatile storage system, first and second substrate channel regions for an unselected NAND string are boosted during programming to inhibit program disturb. The first and second substrate channel regions are created on either side of an isolation word line. During a program pulse time period in which a program pulse is applied to a selected word line, a voltage applied to an unselected word line which extends directly over the second channel region is stepped up to a respective pre-program pulse voltage, at a faster rate at which a voltage applied to an unselected word line which extends directly over the first channel region is stepped up to a respective pre-program pulse voltage. This helps improve the isolation between the channel regions.

Abstract: A system for programming non-volatile storage is proposed that reduces the impact of interference from the boosting of neighbors. Memory cells are divided into two or more groups. In one example, the memory cells are divided into odd and even memory cells; however, other groupings can also be used. Prior to a first trigger, a first group of memory cells are programmed together with a second group of memory cells using a programming signal that increases over time. Subsequent to the first trigger and prior to a second trigger, the first group of memory cells are programmed separately from the second group of memory cells using a programming signal that has been lowered in magnitude in response to the first trigger. Subsequent to the second trigger, the first group of memory cells are programmed together with the second group of memory cells with the programming signal being raised in response to the second trigger.
