To enhance reliability for data.SOLUTION: A randomizer according to an embodiment of the present invention has a first pseudo random number generator, a second pseudo random number generator, and a logic circuit. The first pseudo random number generator generates a plurality of first pseudo random number sequences each having an N1 bit length. The second pseudo random number generator generates a second random number sequence having an N2 bit length (N2>N1). A seed of the second pseudo random number generator is formed of a plurality of third pseudo random number sequences. Each of the third pseudo random number sequences has a bit length of N3 (1
