are specified as reference points only. If
t

the cycle is an early write cycle and the DQ pins
will remain high impedance throughout the entire cycle. If

(for fast page mode cycle only), the cycle is a read-modify-write cycle and the DQ will contain the data read from the selected address.
If neither of the above condition (delayed write) of the DQ (at access time and until CAS or OE goes back to V
IH
) is indeterminate.
