摘要： Disclosed are a program method and a nonvolatile memory device. The method includes receiving program data to be programmed in memory cells; reading the memory cells to judge an erase state and at least one program state; performing a state read operation in which the at least one program state is read using a plurality of state read voltages; and programming the program data in the memory cells using a plurality of verification voltages having different levels according to a result of the state read operation. Also disclosed are methods using a plurality of verification voltages selected based on factors which may affect a threshold voltage shift or other characteristic representing the data of a memory cell after programming.

摘要： A nonvolatile memory includes a plurality of memory blocks and an address decoder. The address decoder is configured to activate a block word line corresponding to the memory blocks in common when one memory block is selected among the memory blocks, supply voltages to word lines of the selected memory block among the memory blocks, and float word lines of an unselected memory block among the memory blocks.

摘要： A nonvolatile memory device performs a read operation comprising first and second intervals. In the first interval the device applies a turn-on voltage to string selection lines and ground selection lines connected to the string selection transistors and the ground selection transistors, respectively. In the second interval, the device applies a turn-off voltage to unselected string selection lines and unselected ground selection lines while continuing to apply the turn-on voltage to a selected string selection line and a selected ground selection line. In both the first and second intervals, the device applies a first read voltage to a selected wordline connected to memory cells to be read by the read operation and applying a second read voltage to unselected wordlines among connected to memory cells not to be read by the read operation.
