Note : 
1.These values are guaranteed by design and are tested on a sample basis only.
2. Although DM is an input -only pin, the input capacitance of this pin must model the input capacitance of  the DQ and DQS pins.
    This is required to match signal propagation times of DQ, DQS, and DM in the system.
3. Unused pins are tied to ground.
4. This parameteer is sampled. For DDR266 and DDR333 VDDQ = +2.5V +0.2V, VDD = +3.3V +0.3V or +0.25V+0.2V. For
    DDR400, VDDQ = +2.6V +0.1V,  VDD = +2.6V +0.1V. For all devices,  f=100MHz, tA=25
°
C, Vout(dc) =  VDDQ/2, Vout(peak to
    peak) = 0.2V. DM inputs are  grouped with I/O pins - reflecting the fact that they are matched in loading (to facilitate trace
    matching at the board level).
