36. These parameters are specified per their average values, however it is understood that the following
relationship between the average timing and the absolute instantaneous timing holds at all times. (Min and
max of SPEC values are to be used for calculations in the table below.)
Example: For DDR2-667, tCH(abs),min = ( 0.48 x 3000 ps ) - 125 ps = 1315 ps
37. tHP is the minimum of the absolute half period of the actual input clock. tHP is an input parameter but
not an input specification parameter. It is used in conjunction with tQHS to derive the DRAM output timing
tQH.
The value to be used for tQH calculation is determined by the following equation;
tHP = Min ( tCH(abs), tCL(abs) ),
where,
tCH(abs) is the minimum of the actual instantaneous clock HIGH time;
tCL(abs) is the minimum of the actual instantaneous clock LOW time;
