  • Method of storing data in nonvolatile memory device and method of operating nonvolatile memory device
    Patent number: 8879318
    Abstract: In a method of storing data in a nonvolatile memory device, a program operation is performed on target memory cells among a plurality of memory cells based on a program voltage. A verification operation is performed on the target memory cells based on a verification voltage to determine whether all of the target memory cells are completely programmed. The verification voltage is changed depending on the program operation.
    Type: Grant

  • Flash memory devices with selective bit line discharge paths and methods of operating the same
    Patent number: 8363482
    Abstract: Provided is a flash memory device that can include a memory cell configured to store data, a local bit line that is connected to the memory cell, a global bit line that is connected to the local bit line, a discharge transistor that is connected to the global bit line, and that is configured to selectively connect the global bit line to a reference level responsive to a discharge control signal, and a discharge control circuit, that is connected to the discharge transistor via the discharge control signal, and that is configured to selectively disable the discharge transistor during an erase interval occurring before a verify interval of an erase verification operation carried out by the flash memory device.
