Any salutations to end a memo?

Can you please list several salutations to end a memo?

I know"sincerely yours", "Best regards", but they sound too formal for
a memo. I have seen people use "cheers" to end a memo.

I wonder if there are other salutations we can use, thanks a lot!

You could say Sincerely or Regards (as Red does). BTW, that would be a closing, not a salutation.

I use Regards in emails and other electronic communication at work.
