control the operations of the RAM blocks.
When a byte-enable bit is de-asserted during a write cycle, the corresponding data
byte output can appear as either a “don’t care” value or the current data at that
location. The output value for the masked byte is controllable using the Quartus II
software. When a byte-enable bit is asserted during a write cycle, the corresponding
data byte output also depends on the setting chosen in the Quartus II software.
Stratix IV 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 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.
