The scrypt hash function uses SHA256 as a subroutine, but also depends on fast access to large amounts of memory rather than depending just on fast arithmetic operations, so it is more difficult to run many instances of scrypt in parallel by using the ALUs of a modern graphics card.Once the difficulty is low, the attacker can mine many fast coins, or in the case of a small chain, an attacker with 51% hash power could reduce the difficulty to 1 and mine a new fork from the genesis block.
