    摘要: A method is provided for operating a memory system. The method includes reading nonvolatile memory cells using a first soft read voltage, a voltage level difference between the first soft read voltage and a first hard read voltage being indicated by a first voltage value; and reading the nonvolatile memory cells using a second soft read voltage paired with the first soft read voltage, a voltage level difference between the second soft read voltage and the first hard read voltage being indicated by a second voltage value. The second voltage value is different than the first voltage value. Also, a difference between the first voltage value and the second voltage value corresponds to the degree of asymmetry of adjacent threshold voltage distributions among multiple threshold voltage distributions set for the nonvolatile memory cells of the memory system.

    摘要: A flash memory device and a method of testing the flash memory device are provided. The flash memory device may include a memory cell array including a plurality of bit lines, a control unit configured to output estimated data and an input/output buffer unit including a plurality of page buffers. Each of the plurality of page buffers corresponds to one of the plurality of bit lines in the memory cell array and is configured to read test data programmed in at least a first page of a memory cell array, compare the read-out test data with the estimated data to determine whether the corresponding bit line is in a pass or failure state and output a test result signal. A voltage of the test result signal is maintained when test data of a second page of the memory cell array is read if the corresponding bit line in the first page is in a failure state.

    摘要: A NOR flash memory device and related programming method are disclosed. The programming method includes programming data in a memory cell and, during a program verification operation, controlling the supply of current from a sense amplifier to the memory cell in relation to the value of the programmed data.

    摘要: In an operating method for a nonvolatile memory device, first random data is sensed from a source area of the memory cell array, the first random data having been generated using first random sequence data. While sensing the first random data, third random sequence data is loaded to a page buffer circuit, the third random sequence data being generated from the first random sequence data and second random sequence data. A logical operation is performed on the sensed first random data and the third random sequence data in the page buffer circuit to generate second random data, and the second random data is programmed to a target area in the memory cell array different from the source area.
