 The new serial interface DDR OPI RAM can improve the issues of the conventional RAM, and has the following advantages:

1. Larger Bandwidth:  Larger than 3Gbps when clock rate is 200MHZ with Octal Bus Double‐Data‐Rate.
2. Big Memory Size:   The 64M memory size is much larger than the other serial interface RAM in the current market.
3. Lower Cost:              Used the advanced DRAM process technology to reduce the chip size, the production cost is close to the cost of DRAM.
4. Smaller size:            The lower pin count package can provide the smaller size and the lower assembly cost than the conventional RAM.
5. Simple Interface :    No refresh cycles needed because of the emerging design technology, the interface is more simple than the conventional RAM.
