Arria II memory blocks support the following clocking modes:

Violating the setup or hold time on the memory block address registers could corrupt
the memory contents. This applies to both read and write operations.
Table 3–9
Arria II memory blocks can implement independent clock mode for true dual-port
memories. In this mode, a separate clock is available for each port (clock A and
clock B). Clock A controls all registers on the port A side; clock B controls all registers
on the port B side. Each port also supports independent clock enables for both port A
and port B registers, respectively. Asynchronous clears are supported only for output
latches and output registers on both ports.
Arria II memory blocks can implement input and output clock mode for true and
simple dual-port memories. In this mode, an input clock controls all registers related
to the data input to the memory block including data, address, byte enables, read
enables, and write enables. An output clock controls the data output registers.
Asynchronous clears are available on output latches and output registers only.
Arria II memory blocks can implement read and write clock mode for simple
dual-port memories. In this mode, a write clock controls the data-input,
write-address, and write-enable registers. Similarly, a read clock controls the
data-output, read-address, and read-enable registers. The memory blocks support
independent clock enables for both the read and write clocks. Asynchronous clears
are available on data output latches and registers only.
