Abstract:
1. A nonvolatile memory apparatus comprising: a nonvolatile memory array including a plurality of nonvolatile memory cells; a power circuit including a first power circuit and a second power circuit; and a voltage controller, wherein said first power circuit can generate an internal operation voltage from an external voltage supply, wherein said second power circuit can generate the internal operation voltage from the external voltage supply, and includes a first power supply path and a second power supply path, an ON resistance value of said first power supply path being less than an ON resistance value of said second power supply path, and said first power supply path and said second power supply path can individually be made active, selectively, based on a voltage level of the external voltage supply, and wherein said voltage controller makes said first power circuit activate for a first operation mode of the nonvolatile memory apparatus, and makes said second power circuit activate for a second operation mode of the nonvolatile memory apparatus.
