1. A programming device comprising:
a plurality of signal lines comprising a first signal line and a common ground line; and
a first programming circuit coupled between the first signal line and the common ground line, and comprising a first configurable switch configured to receive a first switch configuration, the first programming circuit being configured to receive a first power signal from the first signal line and to supply a first programming signal to the first signal line, the first programming signal having a level corresponding to the first switch configuration,
wherein the first programming circuit further comprising:
a voltage divider electrically coupled between the first signal line and the common ground line, and configured to generate an attenuated signal based on the first switch configuration; and
a shunt regulator coupled between the first signal line and the common ground line, and configured to generate the first programming signal based on the attenuated signal.
