Apparatus and system for adjusting internal voltage

摘要

An apparatus for adjusting an internal voltage includes a device characteristic detection circuit which detects a device characteristic, compares the device characteristic with an external clock, and generates a comparison signal, and an internal voltage adjustment circuit which receives an adjustment code generated based on the comparison signal, adjusts a level of an internal voltage, and generates a level-adjusted internal voltage.

1. An apparatus for adjusting an internal voltage, the apparatus comprising:
a device characteristic detection circuit configured to detect a device characteristic in a wafer probing test process, divide, according to a preset ratio, a device characteristic signal generated based on the device characteristic, compare the divided device characteristic signal with an external clock, and generate a comparison signal; and an internal voltage adjustment circuit configured to receive an adjustment code generated based on the comparison signal, adjust a level of an internal voltage, and generate a level-adjusted internal voltage.
