If I change my name, is it still my memoir?

Dear Audrey,

can I write a memoir and change everyone's name, including my own? Or would it have to become fiction at this point, and have to follow the rules for writing a novel.

I don't feel I can use my own name or that of others, because we didn't always obey the law.

Thank you,
Jacqueline
