Well the 13inch Sony DPT-S1 can do that. Presumably the newer Sony DPT-RP1 can do as well.
The notes get saved into pdf. Works quite nicely.
An alternative to Sony would be about to be released ReMarkable e-reader.
Its note taking capabilities are supposed to be excellent from early reviews.

10inch size but priced about the same as Sony 13 inch e-readers, ie expensive.
