Notes:
1. VTT is not applied directly to the device, however tVTD must be greater than or equal to zero to avoid device latch--up.
2. tMRD is required before any command can be applied, and 200 cycles of CK are required before any executable command
3. The two Auto Refresh commands may be moved to follow the first MRS but precede the second PRECHARGE ALL com-
4. AP is A8 for x32, and A10 for x8/x16. Address is A0 to A12 except AP.
