Why does 'thoughts' and 'memories' not part of aggregates?

In MN:44 it is said, > Visākha, the Buddha said that these five grasping aggregates are > identity. That is: form, feeling, perception, choices, and > consciousness. The Buddha said that these five grasping aggregates are > identity.” If feelings are included in identity forming aggregates why 'thoughts' and 'memories' are not included. Afterall, what I think, like, what I feel, makes my self-identity. To quote Rene Decartus, **'I think therefore I am**'. Isn't the constant chattering of mind generate a sense of self. Also, memory of things I did have a powerful effect on sense of self. So, why not included them?
