Abstract
An E-fuse circuit comprising: an E-fuse group, comprising a plurality of E-fuse sections, wherein each one of the E-fuse sections comprises a plurality of E-fuses; a multi-mode latch circuit, configured to receive an input signal to generate a first output signal in a burn in mode, and configured to receive an address to be compared to generate a second output signal in a normal mode; a first logic circuit group, configured to receive a first part of bits of the first output signal to generate a control signal in the burn in mode; and a second logic circuit group, configured to receive the control signal and a second part of bits of the first output signal to generate a selection signal in the burn in mode, to select which one of the E-fuse sections is activated.
