Single-Port RAM
Arria II GX Device Handbook, Volume 1

When using the memory blocks in ROM, single-port, simple dual-port, or true
dual-port mode, you can corrupt the memory contents if you violate the setup or hold
time on any of the memory block input registers. This applies to both read and write
operations.
All memory blocks support single-port mode. Single-port mode allows you to do
either one-read or one-write operation at a time. Simultaneous reads and writes are
not supported in single-port mode.

Note to
(1) You can implement two single-port memory blocks in a single M9K block. For more information, refer to
During a write operation, behavior of the RAM outputs is configurable. If you use the
read-enable signal and perform a write operation with the read enable de-activated,
the RAM outputs retain the values they held during the most recent active read
enable. If you activate read enable during a write operation, or if you are not using the
read-enable signal at all, the RAM outputs either show the new data being written,
the old data at that address, or a don’t care value.
