Many modern platforms contain some logic, that can be (ab)used to do memset() directly in hardware without processor involvement (ie. in parallel with other code). But this tends to require so much setup and IO overhead so it simply isn't worthwhile to do. Integrating memset/bzero logic into memory array itself will increase it's price drastically (but in some special cases it is done, generally when memory array already contains some other expensive non-memory logic).
