Memory is definitely a key component of our thinking processes, but "consciousness" in a philosophical sense is usually taken to refer to the so-called "hard problem" of the phenomenal character of awareness and experience, at its most basic level. The insight that this basic phenomenal character can be impersonal and even momentary in a way that nonetheless fully explains our ordinary experience is quite a substantial simplification! It does seem to make the "hard" problem just a little bit easier, if only by potentially restricting its scope.
