Configuration in Mulitplexed Mode
In Multiplexed Address mode, the Read and Write latencies are increased by one clock cycle. However, the LLDRAM II cycle
time remains the same as when in Nonmultiplexed Address mode.

1. tRC < 20 ns in any configuration is only available with –24 and –18 speed grades.
2. Minimum operating frequency for –18 is 370 MHz.
3. BL = 8 is not available.
4. The minimum tRC is typically 3 cycles, except in the case of a Write followed by a Read to the same bank. In this instance the minimum tRC
is 4 cycles.
