*Note: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage of the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The following sequence is required for POWER UP of IS43R16160A.
1. Apply power and attempt to maintain CKE at a low state (all other inputs may be undefined.)
- Apply VDD before or at the same time as V_DDQ.
- Apply VDDQ before or at the same time as V_TT & Vref.
2. Start clock and maintain stable condition for a minimum of 200us.
3. The minimum of 200us after stable power and clock (CLK, CLK), apply NOP & take CKE high.
4. Precharge all banks.
5. Issue EMRS to enable DLL.(To issue "DLL Enable" command, provide "Low" to A0, "High" to BA0 and "Low" to all of the rest address pins, A1~A11 and BA1)
6. Issue a mode register set command for "DLL reset". The additional 200 cycles of clock input is required to lock the DLL. (To issue DLL reset command, provide "High" to A8 and "Low" to BA0)
7. Issue precharge commands for all banks of the device.
8. Issue 2 or more auto-refresh commands.
9. Issue a mode register set command to initialize device operation. Note1 Every "DLL enable" command resets DLL. Therefore sequence 6 can be skipped during power up. Instead of it, the additional 200 cycles of clock input is required to lock the DLL after enabling DLL.
