REV.0.0(January. 2003) 7 OPERATING AC PARAMETER (AC operating conditions unless otherwise noted) VERSION PARAMETER SYMBOL -13 -12 -10 -10L UNIT NOTE Row active to row active delay tRRD(min) 15 16 20 20 ns 1 RAS to CAS delay tRP(min) 20 20 20 20 ns 1 Row precharge time tRP(min) 20 20 20 20 ns 1 tRAS(min) 45 48 50 50 ns 1 Row active time tRAS(max) 100 ns Row cycle time tRC(min) 65 68 70 70 ns 1 Last data in to row precharge tRDL(min) 2 CLK 2.5 Last data in to Active delay tDAL(min) 2 CLK + tRP - 5 Last data in to new col. address delay tCDL(min) 1 CLK 2 Last data in to burst stop tBDL(min) 1 CLK 2 Col. address to col. address delay tCCD(min) 1 CLK 3 CAS latency=3 2 Number of valid output data CAS latency=2 - 1 ea 4 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. For -8/H/L, tRDL=1CLK and tDAL=1CLK+20ns is also supported . (Recommand : tRDL=2CLK and tDAL=2CLK & 20ns.)
