Clocks required specified by JEDEC functionality and not dependent on any timing parameter.
Timing actually specified by tCKS, clock(s) specified as a reference only at a minimum cycle rate.
Timing actually specified by tWR plus tRP clock(s) specified as a reference only at a minimum cycle rate.
tHZ defines the time at which the output achieves the open circuit condition; it is not a reference to Voh or Vol. The last valid data
element will meet tOH before going high-Z.
Based on tCK = 10ns for –8 and tCK = 7.5ns for –75a
