NOTES (READ CYCLE) 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. If invalid address signals shorter than min. tRC are continuously repeated for over 4us, the device needs a normal read timing(tRC) or needs to sustain standby state for min. tRC at least once in every 4us.

NOTES (WRITE CYCLE)

1. A write occurs during the overlap(tWP) of low CS1 and low WE. A write begins when CS1 goes low and WE goes low with asserting UB or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest transition when CS1 goes high and WE goes high. The tWP is measured from the beginning of write to the end of write. 2. tCW is measured from the CS1 going low to the 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 is applied in case a write ends with CS1 or WE going high.
