Notes:

8. Device is continuously selected. OE, CE = VIL.

9. WE is HIGH for read cycle.

10. Address valid prior to or coincident with CE transition LOW.

11. Data I/O is high impedance if OE = VIH.

12. If CE goes HIGH simultaneously with WE going HIGH, the output remains in a high-impedance state.
