AUTO REFRESH
Single cycle of auto-refresh is initiated with REFA (/CS= /RAS= /CAS= DSF= L, /WE= /CKE= H)
command. The refresh address is generated internally. 2048 REFA cycles within 32ms refresh 16Mbit
memory cells. The auto-refresh is performed on each bank alternately (ping-pong refresh). Before
performing an auto-refresh, both banks must be in the idle state. Additional commands must not be
supplied to the device before tRC from the REFA command.
