97 / 272 page  Altera Corporation 4–31 February 2005 Stratix GX Device Handbook, Volume 1 Stratix GX Architecture The read and write operation of the memory is controlled by the WREN signal, which sets the ports into either read or write modes. There is no separate read enable (RE) signal. Writing into RAM is controlled by both the WREN and byte enable (byteena) signals for each port. The default value for the byteena signal is high, in which case writing is controlled only by the WREN signal. The byte enables are available for the ×18, ×36, and ×72 modes. In the ×144 simple dual-port mode, the two sets of byteena signals (byteena_a and byteena_b) are combined to form the necessary 16 byte enables. Tables 4–9 and 4–10 summarize the byte selection.
