In multiplexed address mode, the read and write latencies are increased by one clock
cycle. However, the RLDRAM cycle time remains the same as when in non-multiplexed
address mode.
1. BL = 8 is not available.
Similar to other commands when in multiplexed address mode, AREF is executed on the
rising clock edge following the one on which the command is issued. However, since
only the bank address is required for AREF, the next command can be applied on the
following clock. The operation of the AREF command and any other command is repre-
sented in Figure 38 on page 61.
