摘要:
Techniques for encoding and decoding fuse data to reduce sense current are disclosed. An embodiment to encode fuse sense data includes inverting each of the bits of the fuse data and using an individual fuse as a flag bit to record the data inversion. The states of the respective fuses may represent different logic states. A fuse may be blown to indicate a logic one and likewise, an unblown fuse may indicate a logic zero. A blown fuse and an unblown fuse may have different current consumption. An unblown fuse may consume more sensing current compared to a blown fuse. Another embodiment to decode the encoded fuse data includes embedded logic circuits and a separate fuse as a flag bit. Encoding and decoding fuse data may reduce fuse sensing current.
