5.4 Default Output V-I Characteristics
DDR2 SDRAM output driver characteristics are defined for full strength default operation as selected by the
EMRS(1) bits A7~A9 =’111’. Figures in Section 5.3.5 and 5.3.6 show the driver characteristics graphically and the
tables sow the same data suitable for input into simulation tools.

The driver characteristics evaluation conditions are:
Nominal Default 25^oC (Tcase), VDDQ = 1.8 V, typical process
Minimum 95^oC (Tcase), VDDQ = 1.7V, slow-slow process
Maximum 0 ^oC (Tcase). VDDQ = 1.9 V, fast-fast process
