FRAM (similar to SRAM) in SOPC?

I'm trying to find out how I can add this FRAM - Ferroelectric RAM (15bit Address, 8bit Data, CE, WE, OE) to my SOPC system. I'm planning on using it on a shared Flash tristate bus (24bit Addr, 16bit Data, WE, OE, CE). I thought maybe a CFI would work for the FRAM, but the address size only goes down to 17 bits. And there is only one SRAM choice (the IDT71V416) without the ability to customize it. Let me know if anyone has any ideas on how to add this without too much trouble. 

 

Thanks 

Andy

Thanks, that worked out great. The only thing I had to do to get it to work, was edit the user logic file and remove the 2bit Byte enable signal and saved the component. It actually didn't look that hard to do on my own, I just haven't previously done any custom user logic.  

 

Thanks again, 

Andy
