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 and voltage condition, tHZ(Max.) is less than tLZ(Min.) both for a given device and from device to device
interconnection.

NOTES (WRITE CYCLE)
1. A write occurs during the overlap of a low CS and a low WE. A write begins at the latest transition among CS going Low and WE
going low : A write end at the earliest transition among CS going high and WE going high, tWP is measured from the begining of write
to the end of write.
2. tCW is measured from the CS going low to end of write.
3. tAS is measured from the address valid to the beginning of write.
4. tWR is measured from the end of write to the address change. tWR applied in case a write ends as CS or WE going high.
