1. Recommend all address pins held LOW during dummy MRS commands.
2. A10–A17 must be LOW.
3. DLL must be reset if
4. CK and CK# must be separated at all times to prevent bogus commands from being issued.
5. The sequence of the eight AUTO REFRESH commands (with respect to the 1,024 NOP com-
mands) does not matter. As is required for any operation, tRC must be met between an
AUTO REFRESH command and a subsequent VALID command to the same bank.
