Note :

2. DPD(Deep Power Down) function is an optional feature, and it will be enabled upon request.

Please contact Samsung for more information.

3. IDD specifications are tested after the device is properly intialized.

4. Input slew rate is 1V/ns.

STABLE is defined as inputs stable at a HIGH or LOW level ;

SWITCHING is defined as: - address and command: inputs changing between HIGH and LOW once per two clock cycles ;

- data bus inputs: DQ changing between HIGH and LOW once per clock cycle; DM and DQS are STABLE.
