Revision A09
Notes:
1.Operation exceeds “ABSOLUTE MAXIMUM RATING” may cause permanent damage to the
devices.
2. All voltages are referenced to VSS
3. These parameters depend on the cycle rate and listed values are measured at a cycle rate with the
minimum values of tCK and tRC.
4. These parameters depend on the output loading conditions. Specified values are obtained with
output open.
5. Power up Sequence
(1) Power up must be performed in the following sequence.
(2) Power must be applied to VCC and VCCQ (simultaneously) while all input signals are held in the
“NOP” state. The CLK signals must be started at the same time.
(3) After power-up a pause of at least 200 μseconds is required. It is required that DQM and CKE
signals then be held ‘high‘ (VCC levels) to ensure that the DQ output is impedance.
(4) All banks must be precharged.
(5) The Mode Register Set command must be asserted to initialize the Mode Register.
(6) A minimum of eight Auto Refresh dummy cycles is required to stabilize the internal circuitry of
the device
