Abstract
Whether a voltage difference reaches a hysteresis voltage of a hysteresis comparator is used to efficiently update a charge of a capacitor and achieve lower power consumption. On the other hand, since the advanced voltage holding circuit is designed to consume lower power, the refresh time must be designed longer, which makes it impossible to do a large number of yield tests. Thus, the test time in conjunction with the relevant application circuit can be greatly shortened, and the testability and reliability of a voltage holding device can be increased.
