  • Patent number: 11514991
    Abstract: A method for detecting and isolating defective memory plane(s) of a non-volatile memory structure during a program verify operation, comprising: initiating, for each plane, a word line verify voltage level scan with a bit scan pass fail criterion and at a starting voltage located within an intended program threshold voltage distribution curve, incrementally decreasing the word line verify voltage by a predetermined offset until a specific condition of the scan is obtained, and storing the voltage at which the specific condition of the scan is obtained, wherein the stored voltage represents a voltage of an upper tail portion of an actual programmed threshold voltage distribution curve of the plane. The stored voltages of all of the memory planes of the structure are compared to determine which plane corresponds to the lowest stored voltage. A “fail” status is applied to the plane corresponding to the lowest stored voltage.

    Abstract: A memory apparatus and method of operation are provided. The apparatus includes memory cells connected to word lines and arranged in strings and configured to retain a threshold voltage. A control circuit is coupled to the word lines and strings and is configured to compute a target word line voltage including a kicking voltage to be applied to selected ones of word lines for a kick time during a read operation. The control circuit extends the kick time by a compensation time to a compensated kick time in response to determining the target word line voltage is not greater than a predetermined voltage design limit.

  • Patent number: 11508450
    Abstract: Aspects of a storage device including a memory and a controller are provided. The memory can include memory dies that draw a current from a current source during a program operation. The controller may monitor for an alarm signal from the memory dies on a first common channel between the controller and the memory dies. The alarm signal indicates that a corresponding memory die is entering an operational state that draws a peak current from the current source for the program operation. The controller can receive, from the memory dies, one or more alarm signals on the first common channel within a predetermined threshold time. The controller can transmit a postpone signal on a second common channel to the memory dies based on the one or more alarm signals received within the predetermined threshold time.

    Abstract: A method of reducing corner rounding during patterning of a substrate to form a prescribed pattern comprising a corner includes dividing the pattern into a first pattern and a second pattern, the first pattern forming a first edge of the corner and the second pattern forming a second edge of the corner. At least a portion of the second pattern overlaps the first pattern such that the first edge intersects with the second edge to form a corner of the prescribed pattern. The method further includes forming the first pattern in a first mask layer disposed on a substrate to expose the substrate and forming the second pattern in the first mask layer to expose the substrate. The substrate exposed through the first mask layer is then etched to obtain the pattern.

  • Patent number: 11417400
    Abstract: Techniques are described for optimizing the peak current during a program operation by controlling a timing and ramp rate of a program-inhibit voltage signal as a function of a program loop number and/or program progress. A transition voltage between a regulated ramp up rate and an unregulated ramp up rate can also be adjusted. For initial and final sets of program loops in a program operation, the ramp up of the program-inhibit voltage signal can occur early so that it overlaps with operations of sense circuits in updating their latches based on results from a verify test in a previous program loop. For an intermediate set of program loops, the overlap is avoided. The ramp up rate can be larger and the transition voltage smaller for the initial and final sets of program loops compared to the intermediate set of program loops.
