Keep nets as short as possible, therefore, DDR2 devices have to be placed close as possible of MIURA.
The layout EBI DDR2 should use controlled impedance traces of ZO = 50Ohm characteristic impedance.
Trace width = 0.13mm: target 50Ohm impedance.
Trace space = 0.30 to 0.38 mm.
Address and control traces may not exceed 1.3 inches (33.0 mm).
Address and control traces must be length-matched to within 0.1 inch (2.54 mm).
Address and control traces must match the data group trace lengths to within 0.25 inches (6.35 mm).
