Claim 10:
11. The anti-fuse memory according to claim 10, wherein the ring oscillator circuit comprises:
a comparison circuit, an output terminal of the comparison circuit being configured to output the initial pulse signal;
a pull-up module connected between an operating power source and an input terminal of the comparison circuit, the pull-up module being enabled in response to the row strobe signal and a first level signal outputted from the comparison circuit and being configured to pull up a voltage across the input terminal of the comparison circuit at a first speed, the first speed being adjustable; and
a pull-down module connected between a ground terminal and the input terminal of the comparison circuit, the pull-down module being enabled in response to the row strobe signal and a second level signal outputted from the comparison circuit and being configured to pull down the voltage across the input terminal of the comparison circuit at a second speed, the second speed being adjustable, and a level value of the first level signal being different from that of the second level signal.
