[AUTO REFRESH]
Command
command. The refresh address is generated internally. 4096 REFA cycles within 64ms refresh
128Mbits 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.
Single cycle of auto-refresh is initiated with a REFA(/CS=/RAS=/CAS=L,/WE=CKE=H)
