† Specifications in this table represent a single SDRAM device.

NOTES:

3. All specifications apply to the device after power-up initialization. All control and address inputs must be stable and valid.

4. Only one bank is activated.

5. tRC ≥ tRCMIN

6. Control and address inputs change state twice during tRC.

7. Control and address inputs change state once every 30 ns.

8. Control and address inputs do not change state (stable).

9. Control and address inputs change state once every cycle.

10. Continuous burst access, nCCD = 1 cycle
