Abstract
A nonvolatile memory apparatus includes: a memory cell coupled to a bit line and a source line; a word line configured to select the memory cell; and a local switch block configured to apply a write voltage, a read voltage, and a source line voltage to the bit line and the source line in response to a local switch select signal. In a write or read operation of the nonvolatile memory apparatus, the word line has a first voltage level, and the local switch select signal has a second voltage level higher than the first voltage level.
