  • Patent number: 12646575
    Abstract: A memory apparatus includes memory cells configured to store a threshold voltage and disposed in memory holes each defining a channel. The memory apparatus also includes a control means configured to apply a first erase voltage to the channel of each of the memory holes including the memory cells in a first loop of an erase operation. The control means verifies the threshold voltage of the memory cells being erased using a target erase verify level voltage and at least one high erase verify level voltage higher than the target erase verify level voltage. The control means slows erasing of ones of the memory cells in a second loop of the erase operation in response to the threshold voltage of the ones of the memory cells being erased being greater than the target erase verify level voltage and less than the at least one high erase verify level voltage.

  • Patent number: 12640206
    Abstract: Technology is disclosed herein for programing memory cells with a post-program erase. In an aspect, the post-program erase includes a bit-level erase that only erases memory cells that are to remain in an erased state after the program operation. Memory cells that are to remain in programmed states may be inhibited from erase during the post-program erase. In an aspect, the post-program erase does not have an erase verify, which saves time and/or power. In an aspect, the post-program erase includes applying a single erase pulse, which saves time and/or power. In an aspect, the duration of the post-program erase pulse is shorter than an erase pulse used prior to programming, which saves time and/or power.

  • Publication number: 20260128115
    Abstract: Technology for retrying failed reads of non-volatile memory such as NAND. The memory system retries the failed read using one or more different read techniques than the failed read until the read is successful. The memory system may use different read reference voltages for read retries than the read reference voltages used in the failed read. After a successful read retry the memory system determines whether the original read failed due to an inherent reliability issue or a physical defect. If there is a physical defect the memory cells may be retired. In an embodiment, the entire block of memory cells having the physical defect is retired. However, if the read failed due to an inherent reliability issue then the memory cells may continue to be used.

  • Patent number: 12592291
    Abstract: A non-volatile memory attempts to read a data set from a plurality of non-volatile memory cells in multiple threshold voltages distributions and determines that the data set was not read successfully due to there being too many errors in the data read. In response to determining that the data set was not read successfully, the system identifies memory cells storing error bits that are in upper tails and lower tails of the threshold voltages distributions. To reduce the number of errors, memory cells storing error bits that are in upper tails have their threshold voltages reduced by bit level erase and memory cells storing error bits that are in lower tails their threshold voltages increased to move the memory cells closer to the center of their respective threshold voltages distributions by bit level program.

  • Patent number: 12580023
    Abstract: A memory apparatus includes memory cells connected to word lines and configured to store a threshold voltage corresponding to data states. The memory cells are disposed in memory holes coupled to bit lines. A control means applies program pulses to selected ones of the word lines. The control means determines when the threshold voltage of each of the memory cells exceeds a lower verify level of one of the data states targeted and maintains a respective count of a number of the program pulses subsequently applied thereto before reaching a lockout state. Each of the program pulses is divided into phases. The control means sets a voltage of one of the bit lines coupled to each of the memory cells at a stepped up level as a function of the respective count and according to each of the phases in which the voltage is set to the stepped up level.
