4. Minimum Impedance Mode when ZQ pin is connected to V
5. Operating current is calculated with 50% read cycles and 50% write cycles.
6. Standby Current is only after all pending read and write burst operations are completed.
7. Programmable Impedance Mode.
only and functional operation of the device at these or any other conditions above those indicated in the operating sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
