Same-Port Read-During-Write Mode
This mode applies to a single-port RAM or the same port of a true dual-port RAM. In
the same port read-during-write mode, there are two output choices: New Data mode
(or flow-through) and Old Data mode. In New Data mode, new data is available on
the rising edge of the same clock cycle on which it was written. In Old Data mode, the
RAM outputs reflect the old data at that address before the write operation proceeds.
When using New Data mode together with byteena, you can control the output of
the RAM. When byteena is high, the data written into the memory passes to the
output (flow-through). When byteena is low, the masked-off data is not written into
the memory and the old data in the memory appears on the outputs. Therefore, the
output can be a combination of new and old data determined by byteena.
