128M GDDR2 SDRAM
K4N26323AE-GC
1. The typical 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 45 ohm@ODT 120 ohm Fix 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 typical 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 45 ohm@ODT 120 ohm Fix variation pullup current from minimum to maximum process, temperature and voltage will lie
within the outer bounding lines of the V-I curve of Figrue b.
5. The 45 ohm@ODT 120 ohm fix 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 45 ohm@ODT 120 ohm fix 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
45 ohm Driver @ODT 120 ohm Fix.
