Nonvolatile memory device and programming method thereof

摘要

A programming method is for programming a nonvolatile memory device including a plurality of strings disposed perpendicular to a substrate and connected between bitlines and a common source line. The programming method includes setting up the common source line to a predetermined voltage, floating the setup common source line, performing a program operation on memory cells connected to a selected wordline, and performing a verify operation on the memory cells.

1. A method of programming a nonvolatile memory device including a plurality of strings disposed perpendicular to a substrate and connected between bitlines and a common source line, the programming method comprising:
setting the common source line to a predetermined voltage; floating the common source line after setting the common source line to the predetermined voltage; performing a program operation on memory cells connected to a selected wordline after floating the common source line; and performing a verify operation on the memory cells to determine whether the program operation was successful.
