• Manufacturer Part Number: HYS64T128020HU-5-B
• Description: 240-Pin unbuffered DDR2 SDRAM Modules
• Manufacturer: QIMONDA [Qimonda AG]

1) For details and notes see the relevant Qimonda component data sheet
2)
3) Timing that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down
4) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
5) The CK / CK input reference level (for timing reference to CK / CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS,
6) Inputs are not recognized as valid until
7) The output timing reference voltage level is
