next cycle during the RAS# HIGH time. Memory cell
data is retained in its correct state by maintaining
power and executing anyRAS# cycle (READ, WRITE) or
RAS# REFRESH cycle (RAS# ONLY, CBR or HIDDEN) so
that all 2,048 combinations of RAS# addresses are ex-
ecuted at least every 32ms, regardless of sequence.
The CBR REFRESH cycle will invoke the refresh counter
for automatic RAS# addressing.
