Power-up state

Output ports are cleared.

  • Registered output ports—Cleared.
  • Unregistered output ports—Read memory contents.
Asynchronous clears Output registers and output latches Output registers and output latches
Write/read operation triggering Rising clock edges Rising clock edges
Same-port read-during-write
  • M20K—output ports set to new data
  • M10K—output ports set to "new data" or "don't care"

(The "don't care" mode applies only for the single-port RAM mode).

Output ports set to "don't care".

Mixed-port read-during-write Output ports set to "old data" or "don't care". Output ports set to "old data", "new data", "don't care", or "constrained don't care".
ECC support

Soft IP support using the Intel® Quartus® Prime software.

Built-in support in x32-wide simple dual-port mode (M20K only).
