... The internal write time of the memory is defined by the overlap of CS Low and W LOW. Both signals must be activated to initiate a write and either signal can terminate a write by going in active mode. The data input setup and hold timing should be refer- enced to the active edge of the signal that terminates the write. Data out is high impedance if OE= V AT60142F/G 9 (1) . ...
