AC OPERATING TEST CONDITIONS
M366S6453CTS
OPERATING AC PARAMETER
Notes : 1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time
(AC operating conditions unless otherwise noted)
Row active to row active delay
RAS to CAS delay
Row precharge time
Row active time
Row cycle time
Last data in to row precharge
Last data in to Active delay
Last data in to new col. address delay
Last data in to burst stop
Col. address to col. address delay
Number of valid output data
AC input levels (Vih/Vil)
Input timing measurement reference level
Input rise and fall time
Output timing measurement reference level
Output load condition
Output
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.
(Fig. 1) DC output load circuit
SAMSUNG recommends tRDL=2CLK and tDAL=2CLK + tRP.
and then rounding off to the next higher integer.
