摘要： A non-volatile memory has its cells' thresholds programmed within any one of a first set of voltage bands partitioned by a first set of reference thresholds across a threshold window. Hard bits are obtained when read relative to the first set of reference thresholds. The cells are read at a higher resolution relative to a second set of reference thresholds so as to provide additional soft bits for error correction. The soft bits are generated by a combination of a first modulation of voltage on a current word line WLn and a second modulation of voltage on an adjacent word line WLn+1, as in a reading scheme known as “Direct-Lookahead (DLA)”.

摘要： Methods and devices for simultaneously verifying or reading multiple states in non-volatile storage are disclosed. Methods and devices for efficiently reducing or eliminating cross-coupling effects in non-volatile storage are disclosed. Methods and devices for efficiently performing reads at a number of voltages to search for the threshold voltage of a memory cell are disclosed. Memory cells on different NAND strings that are read at the same time may be tested for different threshold voltage levels. Memory cells may be tested for different threshold voltages by applying different gate-to-source voltages to memory cells being tested for different threshold voltages. Memory cells may be tested for different threshold voltages by applying different drain to source voltages to the memory cells. Different amounts of compensation for cross-coupling affects may be applied to memory cells on different NAND strings that are read or programmed at the same time. A binary search may be performed.

摘要： A method includes receiving an enumeration message via a host interface of a device that is operatively coupled to a host device and to one or more other devices. The method includes identifying the enumeration message as a command originated by the host device or as a response message from one of the other devices. In response to identifying the enumeration message as a command, an enumeration response message is sent to the host device. The enumeration response message indicates a distinctive device identifier value. The method also includes, in response to identifying the enumeration message as a response message from one of the other devices, reading from the response message an identifier value used by such other device and at least temporarily storing this identifier value at the device to enable the device to select the distinctive device identifier value.

摘要： Methods for operating a non-volatile storage system in which cross-coupling effects are utilized to extend the effective threshold voltage window of a memory cell and to embed additional information within the extended threshold voltage window are described. In some cases, additional information may be embedded within a memory cell storing the highest programming state if the memory cell is in a high boosting environment by splitting the highest programming state into two substates and programming the memory cell to one of the two substates based on the additional information. A memory cell may be in a high boosting environment if its neighboring memory cells are in a high programmed state. Additional information may also be embedded within a memory cell storing the lowest programming state if the memory cell is in a low boosting environment. The additional information may include error correction information.
