WRITE CYCLE SWITCHING CHARACTERISTICS
Notes:
1. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and
2. The internal write time is defined by the overlap of
3. -12 ns device for IS61C1024 only.
4. Tested with
5. Tested with the load in Figure 2. Transition is measured 500 mV from steady-state voltage. Not 100% tested.
