Ching Ting Lu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11656934
    Abstract: Systems, methods, and apparatus including computer-readable mediums for managing open blocks in memory systems such as NAND flash memory devices are provided. In one aspect, a method includes: evaluating a read disturbance level of an open block in a memory, the open block having one or more programmed word lines and one or more blank word lines, and in response to determining that the read disturbance level of the open block is beyond a threshold level, managing each memory cell in at least one of the blank word lines to have a smaller data storing capacity than each memory cell in at least one of the one or more programmed word lines so as to reduce impact of read disturbance.
    Type: Grant

  • Patent number: 11340980
    Abstract: Systems, methods, and apparatus including computer-readable mediums for managing open blocks in memory systems such as NAND flash memory devices are provided. In one aspect, a memory system includes a memory and a memory controller. The memory includes multiple blocks each having a plurality of word lines. The memory controller is coupled to the memory and configured to: evaluate a read disturbance level of an open block, the open block having one or more programmed word lines and one or more blank word lines, and in response to determining that the read disturbance level of the open block is beyond a threshold level, manage each memory cell in at least one of the blank word lines to have a smaller data storing capacity than each memory cell in at least one of the one or more programmed word lines so as to reduce impact of read disturbance.
