You're right, I should have given a more complete account of memory. I personally think that memory is a form of imagination governed by phenomenological feelings.

I don’t deny that brain states matter, talking from the perspective I wrote the article from, I think they define ourselves. I just don’t think that brain states and subjectivity are mutually incompatible. I think subjectivity attaches itself to what is essentially a zombie, comes to be initially defined by that zombie, but also ends up self-constituting itself. I think it matters in as much as that it what we are, what is able to have will, feel pain etc.

I think the account given in the article, if it’s accepted (I personally don’t accept it) offers a good solution to many of the problems of personal identity.
