Abstract

The present invention provides a device and method for programming EFUSE. After continuously inputting the programming information of multiple EFUSE units connected to the digital logic control module to the information input interface of the digital logic control module, the digital logic control The module controls the multiple EFUSE units to automatically program according to the programming information, and there is a clock cycle between each adjacent two EFUSE units that need to be programmed, which meets the timing requirements for programming the EFUSE units, and does not need to The programmed bit retains the programming time, which greatly reduces the programming time of the plurality of EFUSE units and improves the efficiency.

Description

technical field [0001] The invention relates to the field of EFUSE control, in particular to a device and method for programming EFUSE. Background technique [0002] FUSE (electrically programmable fuse, electrically programmable fuse) is a fuse structure generated by electromigration characteristics. Only one fuse of EFUSE can be programmed at a time, and it is compatible with CMOS process technology. EFUSE IP (intellectual property) core can be divided into PIPO (parallel input parallel output) EFUSE IP and SISO (serial input serial output) EFUSE IP. The storage unit of SISO (serial input serial output) EFUSE IP is generally from 8bits to 128bits, and the readout circuit is one, with less interface signals and small area. It is generally used for redundant circuit execution, fine-tuning of integrated circuits, and on-site chip placement repair. [0003] At present, the input of serial input and serial output EFUSE requires the user to control the programming time and pro...
