The extremely high memory bandwidth of the Stratix and Stratix GX
device families is a result of increased memory capacity and speed.

Clear Signals
When applied to input registers, the asynchronous clear signal for the
TriMatrix embedded memory immediately clears the input registers.
However, the output of the memory block does not show the effects until
the next clock edge. When applied to output registers, the asynchronous
clear signal clears the output registers and the effects are seen
immediately.
Parity Bit Support
The memory blocks support a parity bit for each byte. Parity bits are in
addition to the amount of memory in each RAM block. For example, the
M512 block has 576 bits, 64 of which are optionally used for parity bit
