Abstract

A fuse circuit having a fuse unit cell containing two fuses. In the program/write mode, only one of the fuses in the fuse unit cell will be blown. In read mode, since only one fuse is blown, the current that goes through the two fuses in the fuse unit cell will be very small. Hence, the read power consumption for the fuse circuit is also very small and its sensing speed is also very high.
