AUTO REFRESH
Single cycle of auto-refresh is initiated with a REFA
(/CS= /RAS= /CAS= L, /WE= /CKE= H) command.
The refresh address is generated internally. 8192
REFA cycles within 64ms refresh 256M 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 minimum tRFC. Any command must
not be supplied to the device before tRFC from the
REFA command.
