Read & Write Cycle at Same Bank @Burst Length=4
HIGH
: Don't care
*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 clcok.
3. Access time from Row active command. t
CC
*(t
