Auto-Refresh
AUTO REFRESH
Single cycle of auto-refresh is initiated with a REFA (/CS= /RAS= /
CAS= L, /WE= /CKE= H) command. The refresh address is gen-
erated internally. 4096 REFA cycles within 64ms refresh 64M bit
memory cells. The auto-refresh is performed on 4 banks
concurrently. Before performing an auto-refresh, all banks must
be in the idle state. Auto-refresh to auto-refresh interval is mini-
mum tRC. Any command must not be supplied to the device be-
fore tRC from the REFA command.
