  • Patent number: 11127467
    Abstract: Apparatuses and techniques are described for performing an erase operation for a set of memory cells, where the erase operation includes an all word line erase phase to save time followed by an odd-even word line erase phase to improve data retention. A transition to the odd-even word line erase phase can be triggered when the memory cells pass a first verify test which indicates that the threshold voltages of the memory cells have decreased below a first voltage. Or, the transition can be triggered when a threshold number of erase-verify iterations have been performed. The erase operation may be completed when the memory cells pass a second verify test which indicates that the threshold voltages of the memory cells have decreased below a second voltage which is less than the first voltage.

  • Patent number: 10353598
    Abstract: Systems, apparatuses, and methods are provided that refresh data in a memory. Data is programmed into the memory. After which, part or all of the data may be refreshed. The refresh of the data may be different from the initial programming of the data in one or more respects. For example, the refresh of the data may include fewer steps than the programming of the data and may be performed without erasing a section of memory. Further, the refresh of the data may be triggered in one of several ways. For example, after programming the data, the data may be analyzed for errors. Based on the number of errors found, the data may be refreshed.

  • Patent number: 10229744
    Abstract: Techniques are provided for improving the accuracy of read operations of memory cells, where the threshold voltage of the memory cells can shift depending on the coupled up state of the word lines. In one approach, for a read operation, a representative word line voltage in a block is detected and a corresponding set of read voltages is selected. In another approach, a pre-read voltage pulse is applied to a selected word line in response to a read command, just prior to reading the selected cells. In another approach, a voltage pulse is periodically applied to each word line in a block to provide the word lines in a coupled up state. In another approach, a soft erase is performed after a read operation to prevent coupling up of the word lines.

  • Patent number: 10115737
    Abstract: Disclosed herein is a non-volatile storage system with memory cells having a charge storage region that may be configured to store a higher density of charges (e.g., electrons) in the middle than nearer to the control gate or channel. The charge storage region has a middle charge storage material that stores a higher density of charges than two outer charge storage materials that are nearer to the control gate or channel, in one aspect. The charge storage region of one aspect has oxide regions between the middle charge storage material and the two outer charge storage materials. The oxide regions of one embodiment are thin (e.g., less than one nanometer) such that during operation charges may easily pass through the oxide regions. The non-volatile memory cell programs quickly and has high data retention.
