20090128226 | Fuse option circuit - A fuse option circuit including a fuse, a control switch, a latch, and a logical operational controller is provided. The latch stores a selected level. The logical operational controller outputs a selected result signal and feedbacks a control signal to the control switch. The level of the control signal determines whether the control switch is on or off. Therefore, the required level is input to the latch and the working mode having an ultra low current is selected. Furthermore, when the fuse is in an untrimmed state, the level of the selected result signal could be selected by a reset pulse signal of the latch in order to test a product. Afterward, it is determined whether the fuse is trimmed or not. When the fuse is in a trimmed state, the level of the selected result signal is established by a rising edge of the reset pulse signal. | 05-21-2009 |
