= 0V, unless otherwise noted, see notes 5, 12, 13)
Note 5: An initial pause of 500
μ
s is required after power-up followed by a minimum of eight initialization RAS cycles. The initialization cycles should be done either by RAS-only
refresh cycles or by CAS before RAS refresh cycles only.
Note the RAS may be cycled during the initial pause. And any 8 RAS or RAS/CAS cycles are required after prolonged periods (greater than 32ms) of RAS inactivity before
proper device operation is achieved.
After the initialization cycles, RAS should be kept either higher than V
IH(min)
or lower than V
IL(max)
except RAS transition time.
