Half strength driver
1. The nominal pulldown V-I curve for DDR SDRAM devices will be within the inner bounding lines of the V-I curve of Figure a.
2. The full variation in driver pulldown current from minimum to maximum process, temperature and voltage will lie within the outer
bounding lines the of the V-I curve of Figure a.
3. The nominal pullup V-I curve for DDR SDRAM devices will be within the inner bounding lines of the V-I curve of below Figure b.
4. The Full variation in driver pullup current from minimum to maximum process, temperature and voltage will lie within the outer
bounding lines of the V-I curve of Figure b.
5. The full variation in the ratio of the maximum to minimum pullup and pulldown current will not exceed 1.7, for device drain to source
voltage from 0 to VDDQ/2
6. 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 to VDDQ/2
