There is a style of PRNG that is essentially stateless. For example Squirrel3:

In its simplest form this is essentially a hash function that turns a given running index 0 .. N into a repeatable sequence of N+1 pseudo-random numbers. More sophisticated variants take an additional parameter as a seed or as an identifier of different streams of pseudorandom numbers.
Such generators can in theory(!) be non-repeating/aperiodic, because the input index has no inherent upper limit. But they are relatively new and not yet widely explored.
