design without level shifter

Hi all! In my design one of the block which is Flash/OTP(64 kb) is designed for 1.8v, but my other blocks and core are working at 1.2v and IO voltage is also 1.2v. Is it possible to implement the entire design without level shifter (1.2 - 1.8 ) in between the two blocks communicating with each other(one at 1.2v and other at 1.8v). There is a condition that I cant change the IO voltage(1.2v) and my Flash(1.8v) for my entire design. If possible then what are the ways & how? Will the performance degrade? Thanks in adv. Jitendra

You probably need to check timing (you need gates that are characterized for this kind of situation) and you need to check if 1.2V transistors can can handle 1.8V on the gate (which is usually not allowed).
