Although the RLDRAM has the ability to operate with an SRAM interface by accepting
the entire address in one clock, an option in the mode register can be set so that it func-
tions with multiplexed addresses, similar to a traditional DRAM. In multiplexed address
mode, the address can be provided to the RLDRAM in two parts that are latched into the
memory with two consecutive rising clock edges. This provides the advantage of only
needing a maximum of 11 address balls to control the RLDRAM, reducing the number of
