The RLDRAM 3 device must be powered up and initialized in a predefined manner. Op-
erational procedures other than those specified may result in undefined operations or
permanent damage to the device.
The following sequence is used for power-up:
10. The RLDRAM 3 is ready for normal operation.
1. Apply power (V
2. Ensure that RESET# is below 0.2 × V
3. After the power is stable, RESET# must be LOW for at least 200µs to begin the initi-
4. After 100 or more stable input clock cycles with NOP commands, bring RESET#
5. After RESET# goes HIGH, a stable clock must be applied in conjunction with NOP
6. Load desired settings into MR0.
7.
8. After the DLL is reset and Long ZQ Calibration is enabled, the input clock must be
