REV. 1.1 Nov. '99

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
RCD
+ CAS latency - 1) + t
SAC
4. Ouput will be Hi-Z after the end of burst. (1, 2, 4, 8 & Full page bit burst)
5. For -55/60/70/80/10, tRDL=1CLK product can be supported within restricted amounts and it will be distinguished by bucket code
"NV". From the next generation, tRDL will be only 2CLK for every clock frequency
