Note 6: An initial pause of 200μs is required after power-up followed by a minimum of eight initialization cycles (RAS only refresh or CAS before RAS refresh
cycles)
@@@@@@@@@@@@@
@
Note the RAS may be cycled during the initial pause. And eight initialization cycles are required after prolonged periods (greater than
t
REF(max)
) of
RAS inactivity before proper device operation is achieved.
7: Measured with a load circuit equivalent to 100pF, V

=2.4V(I
OH
=-2mA) and V
OL
=0.4V(I

The reference levels for measuring of output signals are 2.0V(V

).
