摘要： A method for controlling a nonvolatile memory device includes requesting a plurality of first sampling values from the nonvolatile memory device, each of the first sampling values representing the number of memory cells having a threshold voltage between a first sampling read voltage and a second sampling read voltage. The first sampling values are processed through a non-linear filtering operation to estimate the number of memory cells having the threshold voltage between the first sampling read voltage and the second sampling read voltage.

摘要： A method is provided for programming a flash memory device including memory cells formed in a direction perpendicular to a substrate, a first sub word line connected to first memory cells and selectable by a first selection line, and a second sub word line connected to second memory cells and selectable by a second selection line, the first and second memory cells being formed at the same level and being supplied with a program voltage at the same time. The method includes performing LSB program operations on the first and second sub word lines by enabling the first and second selection lines, respectively; performing CSB program operations on the first and second sub word lines by enabling the first and second selection lines, respectively; and performing MSB program operations on the first and second sub word lines by enabling the first and second selection lines, respectively.
