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. 4096 REFA cycles within 64ms refresh 64Mbit
memory cells. The auto-refresh is performed on 4 banks concurrently. Before performing an auto-
refresh, all banks must be in idle state. Auto-refresh to auto-refresh interval is minimum tRFC. Any
command must not be issued before tRFC from the REFA command.
