/CS High Pulse Width1)
1. /CS High Pulse Width is defined by /CS or (/UB and /LB) because /UB & /LB can make standby mode when /UB=High and /LB=High.

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.

1. A write occurs during the overlap (tWP) of low /CS and /WE. A write begins when /CS 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 /CS 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 /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.
