摘要： According to the present invention, a programable latch device for use in personalizing a semiconductor device is provided that overcomes the limitations of the prior art. The preferred embodiment programmable latch device can use both fuses and antifuses as programmable elements. The programmable latch device provides a solid digital output indicative of the state of the programmable device, and can be reliably read to provide customization and personalization of associated semiconductor devices. The preferred embodiment programable latch device includes an integrated fuse or antifuse as a programmable element in the latch device. By integrating the programmable element into the latch, device size and complexity is minimized. In particular, the number of transistors required drops considerably when compared to prior art approaches.
