Cyclone III device family M9K memory blocks support the following clocking modes:
■
■
■
■
When using read or write clock mode, if you perform a simultaneous read or write to
the same address location, the output read data is unknown. If you require the output
data to be a known value, use either single-clock mode or I/O clock mode and choose
the appropriate read-during-write behavior in the MegaWizard Plug-In Manager.
Violating the setup or hold time on the memory block input registers might corrupt
the memory contents. This applies to both read and write operations.
Asynchronous clears are available on read address registers, output registers, and
output latches only.
Table 3–5
Table 3–5. Cyclone III Device Family Memory Clock Modes
Cyclone III device family 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.
Cyclone III device family M9K memory blocks can implement input or output clock
mode for FIFO, single-port, true, and simple dual-port memories. In this mode, an
input clock controls all input registers to the memory block, including data, address,
byteena, wren, and rden registers. An output clock controls the data-output
registers. Each memory block port also supports independent clock enables for input
and output registers.
