Read-During-Write Operation at the Same Address

Stratix Device Handbook, Volume 2
When using byte enables in true dual-port RAM mode, the outputs for
the masked bytes on the same port are unknown. (See

Figure 2–15. Same-Port Read-During-Write Functionality
Note to
(1)
Mixed-Port Read-During-Write Mode
This mode is used when a RAM in simple or true dual-port mode has one
port reading and the other port writing to the same address location with
the same clock.
The READ_DURING_WRITE_MODE_MIXED_PORTS parameter for M512
and M4K memory blocks determines whether to output the old data at
the address or a “don’t care” value. Setting this parameter to OLD_DATA
outputs the old data at that address. Setting this parameter to DONT_CARE
outputs a “don’t care” or unknown value. See
sample functional waveforms showing this operation. These figures
assume that the outputs are not registered.
The DONT_CARE setting allows memory implementation in any TriMatrix
memory block. The OLD_DATA setting restricts memory implementation
to only M512 or M4K memory blocks. Selecting DONT_CARE gives the
compiler more flexibility when placing memory functions into TriMatrix
memory.
Outputs are not registered.
