Independent Clock Mode
Cyclone III M9K memory blocks can implement independent clock mode
for true dual-port memories. In this mode, a separate clock is available for
each port (port A and port B). Clock A controls all registers on the port A
side, while clock B controls all registers on the port B side. Each port
also supports independent clock enables for port A and B registers.
Figure 4–14
shows a memory block in independent clock mode.
