CI/O Data Input/Output Capacitance: DQ0-DQ31 — 5 pF
Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.
2. All voltages are referenced to GND.
3. V
IH (max) = VDDQ + 2.0V with a pulse width ≤ 3 ns. The pluse width cannot be greater than one third of the cycle rate.
4. V
IL (min) = GND – 2.0V with a pulse < 3 ns. The pluse width cannot be greater than one third of the cycle rate.
5. An initial pause of 100us is required after power up, followed by two AUTO REFRESH commands, before proper device operation
is ensured. (Vdd and VddQ must be powered up simultaneously. GND and GNDQ must be at same potential.) The two AUTO
REFRESH command wake-ups should be repeated anytime the t
REF refresh requirement is exceeded.
