Figure 3–2. Cyclone III Device Family byteena Functional Waveform
Note to
(1) For this functional waveform, New Data mode is selected.
When a byteena bit is deasserted during a write cycle, the old data in the memory
appears in the corresponding data-byte output. When a byteena bit is asserted
during a write cycle, the corresponding data-byte output depends on the setting
chosen in the Quartus
the old data at that location.
Cyclone III device family M9K memory blocks support packed mode. You can
implement two single-port memory blocks in a single block under the following
conditions:
■
■
Cyclone III device family M9K memory blocks support an active-low address clock
enable, which holds the previous address value for as long as the addressstall
signal is high (addressstall = '1'). When you configure M9K memory blocks in
dual-port mode, each port has its own independent address clock enable.

Each of the two independent block sizes is less than or equal to half of the M9K
block size. The maximum data width for each independent block is 18 bits wide.
Each of the single-port memory blocks is configured in single-clock mode. For
