Read Cycle 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 and voltage condition, tHZ(Max.) is less than tLZ(Min.) both for a given device and from
device to device interconnection.
3. tOE(max) is met only when OE# becomes enabled after tAA(max).
4. If invalid address signals shorter than min. tRC are continuously repeated for over 4s, the device needs a normal
read timing(tRC) or needs to sustain standby state for min. tRC at least once in every 4s.
