*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. Output will be Hi-Z after the end of burst. (1, 2, 4, 8 & Full page bit burst)
