SDRAM 16Mb H-die(x16)
CMOS SDRAM
Rev. 1.5 August 2004
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. Refer to the following clock unit based AC conversion table
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. Parameters depend on programmed CAS latency.
6. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
7. 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.
8. In 100MHz and below 100MHz operating conditions, tRDL=1CLK and tDAL=1CLK + 20ns is also supported.
SAMSUNG recommends tRDL=2CLK and tDAL=2CLK + tRP.
(AC operating conditions unless otherwise noted)
