Notes
26. BGA packaged device is offered in single CE and dual CE options. In this data sheet, for a dual CE device, CE refers to the internal logical combination of CE
27. The internal write time of the memory is defined by the overlap of WE, CE = V
28. Data I/O is high impedance if OE = V
29. If CE goes HIGH simultaneously with WE = V
30. During this period, the I/Os are in output state. Do not apply input signals.

of these signals can terminate a write by going inactive. The data input setup and hold timing must be referenced to the edge of the signal that terminates the write.
