This parameter is sampled and not 100% tested. 3. At any given temperature and voltage condition, tHZ max is less than tLZ min both for a given device and from device to device. 4. A write occurs during the overlap of a low CS1#, a high CS2, a low WE#. A write begins at the latest transition among CS1# going low, CS2 going high and WE# going low. A write ends at the earliest transition among CS1# going high, CS2 going low and WE# going high. tWP is measured from the beginning of write to the end of write. 5. tCW is measured from the later of CS1# going low or CS2 going high to end of write. 6. tAS is measured the address valid to the beginning of write. 7. tWR is measured from the earliest of CS1# or WE# going high or CS2 going low to the end of write cycle. 8. Don’t apply inverted phase signal externally when DQ pin is output mode.

CS2 controls address buffer, WE# buffer, CS1# buffer, OE# buffer and Din buffer. If CS2 controls data retention mode, Vin levels (address, WE#, CS1#, OE#, DQ) can be in the high impedance state. If CS1# controls data retention mode, CS2 must be CS2 ≥ Vcc-0.2V or 0V ≤ CS2 ≤ 0.2V. The other input levels (address, WE# ,OE#, DQ) can be in the high impedance state.
