摘要： A memory device cooperating with a memory controller scrambles each unit of data using a selected scrambling key before storing it in an array of nonvolatile memory cells. This helps to reduce program disturbs, user read disturbs, and floating gate to floating gate coupling that result from repeated and long term storage of specific data patterns. For a given page of data having a logical address and for storing at a physical address, the key is selected from a finite sequence thereof as a function of both the logical address and the physical address. In a block management scheme the memory array is organized into erase blocks, the physical address is the relative page number in each block. When logical address are grouped into logical groups and manipulated as a group and each group is storable into a sub-block, the physical address is the relative page number in the sub-block.

摘要： A power supply and monitoring apparatus such as in a nonvolatile 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.

摘要： Memory die are provided with programmable chip enable circuitry to allow particular memory die to be disabled after packaging and/or programmable chip address circuitry to allow particular memory die to be readdressed after being packaged. In a multi-chip memory package, a memory die that fails package-level testing can be disabled and isolated from the memory package by a programmable circuit that overrides the master chip enable signal received from the controller or host device. To provide a continuous address range, one or more of the non-defective memory die can be re-addressed using another programmable circuit that replaces the unique chip address provided by the pad bonding. Memory chips can also be also be readdressed after packaging independently of detecting a failed memory die.

摘要： Techniques are disclosed herein for programming memory arrays to achieve high program/erase cycle endurance. In some aspects, only selected word lines (WL) are programmed with other WLs remaining unprogrammed. As an example, only the even word lines are programmed with the odd WLs left unprogrammed. After all of the even word lines are programmed and the data block is to be programmed with new data, the block is erased. Later, only the odd word lines are programmed. The data may be transferred to a block that stores multiple bit per memory cell prior to the erase. In one aspect, the data is programmed in a checkerboard pattern with some memory cells programmed and others left unprogrammed. Later, after erasing the data, the previously unprogrammed part of the checkerboard pattern is programmed with remaining cells unprogrammed.

摘要： A circuit for counting in an N-bit string a number of bits M, having a first binary value includes N latch circuits in a daisy chain where each latch circuit has a tag bit that controls each to be either in a no-pass or pass state. Initially the tag bits are set according to the bits of the N-bit string where the first binary value corresponds to a no-pass state. A clock signal having a pulse train is run through the daisy chain to “interrogate” any no-pass latch circuits. It races right through any pass latch circuit. However, for a no-pass latch circuit, a leading pulse while being blocked also resets after a pulse period the tag bit from “no-pass” to “pass” state to allow subsequent pulses to pass. After all no-pass latch circuits have been reset, M is given by the number of missing pulses from the pulse train.

摘要： Methods and non-volatile storage systems are provided for recovering data during a programming of non-volatile storage. Program data that was originally stored in one set of latches may be preserved with a combination of two sets of latches. These two sets of latches may also be used to store verify status during programming of that program data. The original program data may be recovered by performing a logical operation on the data in the two sets of latches. For example, upper page data could be initially stored in one set of latches. While the upper page data is being programmed, that set of latches and another set of latches are used to store verify status with respect to the upper page data. If a program error occurs while the upper page data is being preserved, it may be recovered by performing a logical operation on the two sets of latches.
