Abstract
A nonvolatile memory device includes: a driving voltage generation unit configured to generate a driving voltage of a core bias line included in a memory cell current path; a comparison unit configured to compare a voltage level of the core bias line with a predetermined limit level in response to a virtual negative read signal; and a compensation driving unit configured to compensation-drive the core bias line in response to an output signal of the comparison unit.
