Table 2–5. Truth Table for the ECC Status Flags
When ECC is engaged, you cannot use the byte enable feature. Also, when ECC is
engaged, read-during-write old data mode is not supported.
Figure 2–6
Stratix V embedded memory blocks allow you to implement fully synchronous
SRAM memory in multiple modes of operation. M20K blocks do not support
asynchronous memory (unregistered inputs). MLABs support asynchronous
(flow-through) read operations.
Depending on which memory block you target, you can use the following modes:

No error.
Illegal.
A correctable error occurred and the error has been
corrected at the outputs; however, the memory array
has not been updated.
An uncorrectable error occurred and uncorrectable
data appears at the outputs.
