In true dual-port configuration, the RAM outputs can only be configured
for read-during-write mode. This means that during write operation,
data being written to the A or B port of the RAM flows through to the A
or B outputs, respectively. When the output registers are bypassed, the
new data is available on the rising edge of the same clock cycle it was
written on. For waveforms and information on mixed-port read-during-
write mode, see
page
Potential write contentions must be resolved external to the RAM because
writing to the same address location at both ports results in unknown
data storage at that location. Data is written on the rising edge of the write
clock for the M-RAM block. For a valid write operation to the same
address of the M-RAM block, the rising edge of the write clock for port A
must occur following the maximum write cycle time interval after the
rising edge of the write clock for port B. Since data is written into the
M512 and M4K blocks at the falling edge of the write clock, the rising
edge of the write clock for port A should occur following half of the
maximum write cycle time interval after the falling edge of the write clock
for port B. If this timing is not met, the data stored in that particular
address is invalid.
See the Stratix Device Family Data Sheet section of the Stratix Device
Handbook, Volume 1 or the Stratix GX Device Family Data Sheet section of
the Stratix GX Device Handbook, Volume 1 for the maximum synchronous
write cycle time.
