Abstract
An anti-fuse circuit including a programmable module, a read module, and a control module is provided. The programmable module has a plurality of data cells. The read module is coupled to the programmable module. During a normal operation, the read module distinguishes which one or more of the data cells are stressed. The control module is coupled to the programmable module. During a stress operation, the control module controls each stressed data cell to be coupled to a high voltage, a low voltage, and a control voltage. The first end of each stressed data cells is coupled to the low voltage, the second end of each stressed data cells is coupled to the high voltage, and the control end of each stressed data cells is coupled to the control voltage during the stress operation.
