Claim 16:
17. The signal transmission method of claim 16, wherein:
Step S5 comprises:
S51: controlling the logic circuit to write the first sampled voltage to the RRAM, and decreasing the voltage of the lower electrode of the RRAM to a third voltage, wherein a difference between the third voltage and the voltage of the upper electrode of the RRAM is greater than the voltage threshold;
S52: increasing the voltage of the lower electrode of the RRAM to the second voltage, so that a difference between the voltage of the upper electrode and the voltage of the lower electrode of the RRAM is less than the voltage threshold;
Step S9 comprises:
S91: controlling the logic circuit to write the second sampled voltage into the RRAM, and decreasing the voltage of the lower electrode of the RRAM to the third voltage; and
S92: increasing the voltage of the lower electrode of the RRAM to the second voltage, so that the difference between the voltage of the upper electrode and the voltage of the lower electrode of the RRAM is less than the voltage threshold.
