Weak Mode Pulldown and Pullup Characteristics
Weak Strength Pulldown Characteristics
1. The weak pulldown V-I curve for DDR SDRAM devices is expected, but not guaranteed, to lie within the
inner bounding lines of the V-I curve
2. The weak pullup V-I curve for DDR SDRAM devices is expected, but not guaranteed, to lie within the
inner bounding lines of the V-I curve.
3. The full variation in driver pullup current from minimum to maximum process, temperature, and voltage lie
within the outer bounding lines of the V-I curve.
4. The full variation in the ratio of the maximum to minimum pullup and pulldown current does not exceed
1.7, for device drain to source voltages from 0.1 to 1.0.
5. The full variation in the ratio of the nominal pullup to pulldown current should be unity
±
10
%
, for device
drain to source voltages from 0.1 to 1.0V.
