Figure 7. Memory READ Cycle
Note: WE is high for a READ cycle.
Figure 8. Memory WRITE Cycle, WRITE Enable Controlled
Note: 1. OE = VIH or VIL. If OE = VIH during a WRITE cycle, the output buffers remain in a high impedance state.
2. If the CE low transition occurs simultaneously with or later than the WE low transition in WE Controlled WRITE, the output buffers
remain in a high impedance state during this period.
3. If the CE high transition occurs simultaneously with the WE high transition, the output buffers remain in a high impedance state
during this period.
