NOTE:
1. This table applies when CKE
n-1
was HIGH and CKE
n
is HIGH (see Truth Table 2) and after
t
XSNR has been
met (if the previous state was self refresh).
2. This table describes alternate bank operation, except where noted (i.e., the current state is for bank
n
and
the commands shown are those allowed to be issued to bank
m,
assuming that bank
m
is in such a state
that the given command is allowable). Exceptions are covered in the notes below.
