Claim 18:
19. The signal transmission method according to claim 18, wherein step S5 comprises:
S51: turning on the row selecting transistor, writing 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 upper electrode of the RRAM is greater than the voltage threshold;
S52: turning off the row selecting transistor, and 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 of the RRAM and the voltage of the lower electrode of the RRAM is less than the threshold voltage;
Step S9 comprises:
S91: turning on the row selecting transistor, writing the second sampled voltage to the RRAM, and decreasing the voltage of the lower electrode of the RRAM to the third voltage; and
S92: turning off the row selecting transistor, and 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 of the RRAM and the voltage of the lower electrode of the RRAM is less than the voltage threshold.
