Stratix Device Handbook, Volume 1
Independent Clock Mode
The memory blocks implement independent clock mode for true dual-
port memory. In this mode, a separate clock is available for each port
(ports A and B). Clock A controls all registers on the port A side, while
clock B controls all registers on the port B side. Each port, A and B, also
supports independent clock enables and asynchronous clear signals for
port A and B registers.
