NOTES:
1. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output voltage levels.
2. At any given temperature adn voltage condition, tHZ (MAX) is less than tLZ (MIN) both for a given device and from device to
device interconnection.
3. A write occurs during the overlap of a low CE\ adn a low WE\. A write begins at the latest transistion among CE\ going Low and
WE\ going Low: A write end at the earliest transistion among CE\ going High and WE\ going High, tWP is measured from the
beginning of write to the end of write.
4. tCW is measured from the CE\ going Low to end of write.
5. tAS is measured from the address valid to the beginning of write.
6. tWR is measure from the end of write to the address change. tWR applied in case a write ends are CE\ or WE\ going High.
