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

    +CAS latency-1)+

    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.
