Clock Cycle Time (tCK) 6ns (min.) / 12ns (max.)
Row Cycle Time (tRC) 60ns (min.)
Refresh Row Cycle Time (tRFC) 72ns (min.)
Row Active Time (tRAS) 42ns (min.) / 70,000ns (max.)
Single Power Supply of +2.5V (+/- .2V)
Power (IDD0) 8.900 W (operating)
UL Rating 94 V - 0

Note: The module defined in this data sheet is one of several configurations available under this part number. While
all configurations are compatible, the DRAM combination and/or the module height may vary from what is described
here. However, in no configuration will the module height exceed 1.200" (30.48mm).
