All voltages referenced to Vss.
An initial pause of 100
μ
s is required after power-up, followed by two AUTO REFRESH commands, before proper device operation
is ensure. (Vdd and VddQ must be powered-up simultaneously Vss and VssQ must be at the same potential.) The two AUTO
REFRESH command wake-ups should be repeated any time the
t
REF refresh requirement is exceeded.
Icc specifications are tested after the device is properly initialized. tCK= 10ns for –8 and tCK=7.5ns for –75A.
