READ CYCLE NO. 2
Notes:
1. WE is HIGH for a Read Cycle.
2. The device is continuously selected. OE, CE1 = V
3. Address is valid prior to or coincident with CE1 LOW and CE2 HIGH transitions.

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. 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 CE1 LOW, CE2 HIGH and WE LOW. All signals must be in valid states to
4. Tested with OE HIGH.
