    摘要: Techniques are disclosed herein for automatically self-disabling a memory die in the event that a programmable element on the memory die for indicating whether the memory die is defective cannot be trusted. Memory die are provided with chip enable circuitry to allow particular memory die to be disabled. If the programmable element can be trusted, the state of the programmable element is provided to the chip enable circuitry to enable/disable the memory die based on the state. However, if the programmable element cannot be trusted, then the chip enable circuitry may automatically disable the memory die. This provides a greater yield for multi-chip memory packages because packages having memory die with a programmable element that cannot be trusted can still be used.

    摘要: High performance non-volatile memory devices have the programming voltages trimmed for individual types of memory pages and word lines. A group of word lines within each erasable block of memory are tested in successive program loops to minimize the problem of incurring excessive number of erase/program cycles. An optimum programming voltage for a given type of memory pages is derived from statistical results of a sample of similar of memory pages.

    摘要: An error recovery technique is used on marginal nonvolatile memory cells. A marginal memory cell is unreadable because it has a voltage threshold (VT) of less than zero volts. By biasing adjacent memory cells, this will shift the voltage threshold of the marginal memory cells, so that it is a positive value. Then the VT of the marginal memory cell can be determined. The technique is applicable to both binary and multistate memory cells.

    摘要: In a non-volatile memory, a selected page on a word line is successively programmed by a series of voltage pulses of a staircase waveform with verifications in between the pulses until the page is verified to a designated pattern. The programming voltage at the time the page is programmed verified will be used to estimate the initial value of a starting programming voltage for the page. The estimation is further refined by using the estimate from a first pass in a second pass. Also, when the test is over multiple blocks, sampling of word lines based on similar geometrical locations of the blocks can yield a starting programming voltage optimized for faster programming pages.

    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 readdressed 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: A method and apparatus provide an improved identification and isolation of defective blocks in non-volatile memory devices having a plurality of user accessible blocks of non-volatile storage elements where each block also has an associated defective block latch. The method provides for sensing each defective block latch to determine whether the defective block latch was set due to a defect, and storing, in temporary on chip memory, address data corresponding to each set latch. The method further involves retrieving the address data and disabling defective blocks based upon the address data. A non-volatile memory device is also described having a controller which senses the defective block latches, stores address data for each block having a set latch, and subsequently retrieves the stored address data to set the defective block latches based upon the address data.
