| 摘要 | An apparatus for generating a random number has high entropy. The apparatus includes a plurality of random number generators, each of which generates a metastability signal and generates a random number by using the generated metastability signal in a first mode, and in a second mode, the plurality of random number generators are connected to one another to operate as a ring oscillator. | ||

| 主权项 | 1. An apparatus for generating a random number, which comprises a plurality of random number generators, wherein each of the plurality of random number generators generates a metastability signal and generates a random number by using the generated metastability signal in a first mode, and wherein the plurality of random number generators are connected to each other to operate as a ring oscillator in a second mode, wherein each of the plurality of random number generators comprises:a metastability generation unit generating and outputting the metastability signal; andan amplifier amplifying an output signal of the metastability generation unit. | ||
