Zero static power programmable fuse cell for integrated circuits

摘要

A software programmable fuse cell which reduces or eliminates static power consumption is disclosed. The programmable fuse cell can be operated in programmable and non-programmable operating modes. Depending on the operating mode, the fuse cell output is determined by the actual state of the fuse or which fuse state the fuse cell is simulating. To reduce static power consumption, a latch is used to store the actual or simulated fuse state.
