HYS64D128320HU-5-C QIMONDA [Qimonda AG], HYS64D128320HU-5-C Datasheet - Page 21

• Manufacturer Part Number: HYS64D128320HU-5-C
• Description: 184-Pin Unbuffered Double Data Rate SDRAM
• Manufacturer: QIMONDA [Qimonda AG]

1) 0 °C ≤ T
2) Input slew rate ≥ 1 V/ns for DDR400, DDR333
3) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference level for signals
4) Inputs are not recognized as valid until V
5) The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (note 3) is V
6) For each of the terms, if not already an integer, round to the next highest integer. t
7) t
