WRITE CYCLE SWITCHING CHARACTERISTICS
Notes:
1. Test conditions for IS61WV6416BLL assume signal transition times of 1.5ns or less, timing reference levels of 1.25V, input
2. Tested with the load in Figure 1b. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE LOW and UB or LB, and WE LOW. All signals must be in valid states to
