Nonvolatile memory device

A nonvolatile memory device, comprising:

• a plurality of programming current driving units configured to supply memory cells with a programming current corresponding to a write data;
• a common programming current controlling unit configured to generate a common control voltage for controlling the programming current;
• a switching unit configured to transfer the common control voltage to the programming current driving unit selected among the plurality of programming current driving units by a plurality of driving selection signals;
• and
• a driving selection signal generating unit configured to generate the plurality of driving selection signals for selecting the programming current driving unit to be enabled according to a write address and a write verification result.
