Embodiment Construction
[0018] Such as figure 2 As shown, the present invention adds a parallel-to-serial conversion circuit (parallel to serial) after the original n-bit fuse circuit to convert the n-bit parallel output signal of the n-bit fuse circuit into a 1-bit serial signal. In this way, a 1-bit serial signal only needs a 1-bit level conversion circuit to realize signal conversion between different power sources. The 1-bit serial signal output by the level conversion circuit is connected to the serial→parallel conversion circuit (serial to parallel), through the serial→parallel conversion circuit, the 1-bit serial signal is converted into an n-bit parallel signal, and output to other circuits for use . Correspondingly, an additional control circuit needs to be set up to control the parallel-to-serial conversion circuit and the serial-to-parallel conversion circuit.
[0019] Such as image 3 As shown, the present invention provides a basic structure of a control circuit. The main function o...

The invention proposes a new signal conversion circuit applied to a fuse circuit. The signal conversion circuit applied to the fuse circuit mainly includes a control circuit, a 1-bit level conversion circuit, a parallel-to-serial circuit and a serial-to-parallel circuit, and the control circuit controls the parallel-to-serial circuit and the serial-to-parallel circuit, so that The m-bit signal output by the n-bit fuse circuit is converted into a serial signal by a parallel-to-serial circuit, and then the level conversion is realized by a 1-bit level conversion circuit, and finally the level-converted signal is paralleled to m bits by a serial-to-parallel circuit output, where m≤n. The present invention realizes the functions of the prior art only by using a 1-bit level conversion circuit; although the control circuit, the parallel-to-serial circuit and the serial-to-parallel circuit are added, compared with the n-bit level conversion circuit, the increased circuit area Small and consumes little power.
Description
technical field [0001] The invention relates to the field of electronic chips, in particular to a signal conversion circuit structure applied to a fuse circuit. Background technique [0002] In the design and manufacture of chips, fuse circuits are often used. The main function of the fuse is: after the chip production is completed, the fuse needs to be switched according to the test result or function setting. Its switching is mainly to blow the preset fuse in the chip by laser, so as to change the hard connection of the circuit and change the working state or function of the circuit. [0003] Due to different working power sources, the output signal of the fuse circuit cannot be directly used by the circuit. The signal of the fuse circuit needs to be processed by the level conversion circuit before being output to other circuits for use. Usually, each bit of fuse circuit is connected to a bit of level conversion circuit. Such as figure 1 As shown, it is the fuse circu...
