Notes :  
1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time  
and then rounding off to the next higher integer.  
2. Minimum delay is required to complete write.  
3. All parts allow every cycle column address change.  
4. In case of row precharge interrupt, auto precharge and read burst stop.  
5. In 100MHz and below 100MHz operating conditions, tRDL=1CLK and tDAL=1CLK + 20ns is also supported.  
SAMSUNG recommends tRDL=2CLK and tDAL=2CLK + tRP.

3. Assumed input rise and fall time (tr & tf) = 1ns.  
If tr & tf is longer than 1ns, transient time compensation should be considered,  
i.e., [(tr + tf)/2-1]ns should be added to the parameter.

No operation command  
Notes :  
1. OP Code : Operand code  
A0 ~ A12 & BA0 ~ BA1 : Program keys. (@ MRS)  
2. MRS can be issued only at all banks precharge state.  
A new command can be issued after 2 CLK cycles of MRS.  
3. Auto refresh functions are as same as CBR refresh of DRAM.  
The automatical precharge without row precharge command is meant by "Auto".  
Auto/self refresh can be issued only at all banks precharge state.  
4. BA0 ~ BA1 : Bank select addresses.  
If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected.  
If BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected.  
If BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected.  
If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected.  
If A10/AP is "High" at row precharge, BA0 and BA1 is ignored and all banks are selected.  
5. During burst read or write with auto precharge, new read/write command can not be issued.  
Another bank read/write command can be issued after the end of burst.  
New row active of the associated bank can be issued at tRP after the end of burst.  
6. Burst stop command is valid at every burst length.  
7. DQM sampled at positive going edge of a CLK and masks the data-in at the very CLK (Write DQM latency is 0),  
but makes Hi-Z state the data-out of 2 CLK cycles after. (Read DQM latency is 2)
