MLABs. Falling clock edges triggers the write operation in MLABs.
Arria II M9K and M144K blocks support packed mode. The packed mode feature
packs two independent single-port RAMs into one memory block. The Quartus II
software automatically implements the packed mode where appropriate by placing
the physical RAM block into true dual-port mode and using the MSB of the address to
distinguish between the two logical RAMs. The size of each independent single-port
RAM must not exceed half of the target block size.
Arria II memory blocks support address clock enable, which holds the previous
address value for as long as the signal is enabled (addressstall = 1). When you
configure the memory blocks in dual-port mode, each port has its own independent
address clock enable. The default value for the address clock enable signal is low
(disabled).
