1. Operation within the tRCD(max.) limit ensures that tRAC(max.) can be met. tRCD(max.) is specified as a reference point only. If tRCD
is greater than the specified tRCD(max.) limit, then access time is controlled by tCAC
2. Operation within the tRAD(max.) limit ensures that tRAC(max.) can be met. tRAD(max.) is specified as a reference point only. If tRAD
is greater than the specified tRAD(max.) limit, then access time is controlled by tAA
.
.
3. Measured with the specified current load and 100pF at VOL = 0.8V and VOH = 2.0V.
4. Either tRCH or tRRH must be satisfied for a read cycle.
5. tOFF (max) and tOEZ (max) define the time at which the output achieves the open circuit condition and are not referenced to output
voltage levels.
6. tOFF is referenced from the rising edge of RAS or CAS, which ever is last.
7. Either tCDD or tOED must be satisfied.
