Read & Write Cycle at Same Bank @Burst Length = 4
*Note:
1.Minimum row cycle times is required to complete internal DRAM operation.
2.Row precharge can interrupt burst on any cycle. [CAS Latency-1] number of valid output data is available after Row
precharge. Last valid output will be Hi-Z(

) after the clock.
3.Access time from Row active command. tcc*

4.Ouput will be Hi-Z after the end of burst.(1,2,4,8 bit burst)
Burst can’t end in Full Page Mode.
