[AUTO REFRESH]
Auto-refresh cycle 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
256 Mbits memory cells. The auto-refresh is performed on 4 banks concurrently. Before performing an auto
refresh, all banks must be in the idle state. The minimum internal between auto-refresh is tRFC . No
command is allowed within tRFC time after the REFA command.
