  • Patent number: 12658268
    Abstract: In an example method of operating a nonvolatile memory device, an erase command and a block address designating a target memory block from a plurality of memory blocks are received. Whether the target memory block is an open block including at least one erased word-line is determined based on the erase command and the block address. A pre-program voltage having a first voltage level is applied to word-lines of the target memory block during pre-program period of a erase loop based on the target memory block being a closed block including only programmed word-lines. A pre-program voltage having a second voltage level greater than the first voltage level is applied to a portion of a region, including the at least one erased word-line, of the target memory block during the pre-program period based on the target memory block being the open block.

  • Patent number: 12412633
    Abstract: The present disclosure provides apparatuses and methods for operating a flash memory for programming operating system (OS) data before an surface mount technology (SMT) process. In some embodiments, the method includes erasing a plurality of memory cells in a memory block, reducing a lateral charge loss of the plurality of memory cells due to high temperature degradation during the SMT process by applying a pre-program voltage to word lines coupled to the memory block, and performing multi-bit programming of the OS data in the plurality of memory cells, prior to performing the SMT process. The applying of the pre-program voltage causes threshold voltages of the plurality of memory cells to increase.
