Patent number: RE45497Abstract: Program disturb is reduced in a non-volatile storage system by programming storage elements on a selected word line WLn in separate groups, according to the state of their WLn?1 neighbor storage element, and applying an optimal pass voltage to WLn?1 for each group. Initially, the states of the storage elements on WLn?1 are read. A program iteration includes multiple program pulses. A first program pulse is applied to WLn while a first pass voltage is applied to WLn?1, a first group of WLn storage elements is selected for programming, and a second group of WLn storage elements is inhibited. Next, a second program pulse is applied to WLn while a second pass voltage is applied to WLn?1, the second first group of WLn storage elements is selected for programming, and the first group of WLn storage elements is inhibited. A group can include one or more data states.Type: GrantFiled: March 31, 2014Date of Patent: April 28, 2015Assignee: SanDisk Technologies Inc.Inventors: Deepanshu Dutta, Henry Chin

Patent number: RE45520Abstract: In a programming operation, selected storage elements on a selected word line are programmed while unselected storage elements on the selected word line are inhibited from programming by channel boosting. To provide a sufficient but not excessive level of boosting, the amount of boosting can be set based on a data state of the unselected storage element. A greater amount of boosting can be provided for a lower data state which represents a lower threshold voltage and hence is more vulnerable to program disturb. A common boosting scheme can be used for groups of multiple data states. The amount of boosting can be set by adjusting the timing and magnitude of voltages used for a channel pre-charge operation and for pass voltages which are applied to word lines. In one approach, stepped pass voltages on unselected word lines can be used to adjust boosting for channels with selected data states.Type: GrantFiled: March 31, 2014Date of Patent: May 19, 2015Assignee: SanDisk Technologies Inc.Inventors: Deepanshu Dutta, Jeffrey W Lutze, Grishma Shah

Patent number: RE45567Abstract: A power supply and monitoring apparatus such as in a non-volatile memory system. A power supply circuit provides power to a large number of sense modules, each of which is associated with a bit line and a string of non-volatile storage elements. During a sensing operation, such as a read or verify operation, a discharge period is set in which a sense node of each sense module discharges into the associated bit line and string of non-volatile storage elements, when the string of non-volatile storage elements, is conductive. This discharge sinks current from the power supply, causing a perturbation. By sampling the power supply, a steady state condition can be detected from a rate of change. The steady state condition signals that the discharge period can be concluded and data can be latched from the sense node. The discharge period automatically adapts to different memory devices and environmental conditions.Type: GrantFiled: February 11, 2014Date of Patent: June 16, 2015Assignee: SANDISK TECHNOLOGIES INC.Inventors: Tien-chien Kuo, Man L. Mui

Patent number: RE45603Abstract: A set of non-volatile storage elements are subjected to a programming process in order to store data. During the programming process, one or more verification operations are performed to determine whether the non-volatile storage elements have reached their target condition to store the appropriate data. Programming can be stopped when all non-volatile storage elements have reached their target level or when the number of non-volatile storage elements that have not reached their target level is less than a number or memory cells that can be corrected using an error correction process during a read operation (or other operation). The number of non-volatile storage elements that have not reached their target level can be estimated by counting the number of non-volatile storage elements that have not reached a condition that is different (e.g., lower) than the target level.Type: GrantFiled: May 29, 2014Date of Patent: July 7, 2015Assignee: SANDISK TECHNOLOGIES INC.Inventor: Gerrit Jan Hemink

Patent number: RE45700Abstract: Methods and non-volatile storage systems are provided for using compensation that depends on the temperature at which the memory cells were programmed. Note that the read level compensation may have a component that is not dependent on the memory cells' Tco. That is, the component is not necessarily based on the temperature dependence of the Vth of the memory cells. The compensation may have a component that is dependent on the difference in width of individual Vth distributions of the different states across different temperatures of program verify. This compensation may be used for both verify and read, although a different amount of compensation may be used during read than during verify.Type: GrantFiled: May 21, 2014Date of Patent: September 29, 2015Assignee: SanDisk Technologies Inc.Inventor: Deepanshu Dutta

Patent number: RE45731Abstract: During programming of storage elements, channel-to-floating gate coupling effects are compensated to avoid increased programming speed and threshold voltage distribution widening. In connection with a programming iteration, unselected bit lines voltages are stepped up to induce coupling to selected bit lines, and the amount of coupling which is experienced by the selected bit lines is sensed. When a program pulse is applied, voltages of the selected bit lines are set based on the amount of coupling. The bit line voltage is set higher when more coupling is sensed. The amount of coupling experience by a given selected bit line is a function of its proximity to unselected bit lines. One or more coupling thresholds can be used to indicate that a given selected bit line has one or two adjacent unselected bit lines, respectively.Type: GrantFiled: May 23, 2014Date of Patent: October 6, 2015Assignee: SanDisk Technologies Inc.Inventor: Yan Li

Patent number: RE45800Abstract: A system and method for physical shared channel allocation in a UMTS wireless communication system. A physical shared channel allocation message (220) is sent containing a plurality of occurrences of allocated physical resources and TFCS IDs; and, at a radio unit (130A), the sent physical shared channel allocation message is received and the plurality of occurrences of allocated physical resources and TFCS IDs contained therein are processed, thereby allowing a plurality of CCTrCHs to be allocated with a single physical shared channel allocation message (220).

Patent number: RE45871Abstract: 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.Type: GrantFiled: May 21, 2014Date of Patent: January 26, 2016Assignee: SanDisk Technologies Inc.Inventors: Chun-Hung Lai, Deepanshu Dutta, Shinji Sato, Gerrit Jan Hemink

Patent number: RE45910Abstract: 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.Type: GrantFiled: May 29, 2014Date of Patent: March 1, 2016Assignee: SANDISK TECHNOLOGIES INC.Inventors: Yingda Dong, Shih-Chung Lee, Ken Oowada
