You can selectively enable asynchronous clears per logical memory via the Quartus II
RAM MegaWizard Plug-In Manager.

Stratix III M144K blocks have built-in support for error correction code (ECC) when in
×64-wide simple dual-port mode. ECC allows you to detect and correct data errors in
the memory array. The M144K blocks have a single-error-correction
double-error-detection (SECDED) implementation. SECDED can detect and fix a
single-bit error in a 64-bit word or detect two-bit errors in a 64-bit word. It cannot
detect three or more errors.
The M144K ECC status is communicated via a three-bit status flag
eccstatus[2..0]. The status flag can be either registered or unregistered. When
registered, it uses the same clock and asynchronous clear signals as the output
registers. When not registered, it cannot be asynchronously cleared.

Table 4–3. Truth Table for ECC Status Flags
You cannot use the byte-enable feature when ECC is engaged.
Read during write “old data” mode is not supported when ECC is engaged.
