NOTES (READ CYCLE)
1. t HZ and tOHZ are defined as the outputs achieve the open circuit conditions and are not referanced to output voltage levels.
2. At any given temperature and voltage condition, t HZ(Max.) is less than t LZ(Min.) both for a given device and from device to device
interconnection.

NOTES (WRITE CYCLE)
1. A write occurs during the overlap(t WP) of low CS and low WE. A write begins at the latest transition among CS goes low and
WE goes low. A write ends at the earliest transition when CS goes high and WE goes high. The tWP is measured from the
beginning of write to the end of write.
2. t CW is measured from the CS going low to end of write.
3. t A S is measured from the address valid to the beginning of write.
4. t WR is measured from the end or write to the address change. tWR applied in case a write ends as CS or WE going high.
