The contents of the memory at 000015D2 can not be accessable to HHHn, as the input is described as DDD and not DDDn, so the input doesn't change between instances, and thus CAN'T contain that memory that changes, and thus is not valid to be part of the input. Thus we also have that HHH∞ can not exist, so both your premises just fail to be possible. Sorry, you are just repeating your error because apparently you just can't learn.
