Design and synthesis of DRAM-based memory systems has been a difficult task in high-level system synthesis because of the relatively complex protocols involved. In this paper, we illustrate a method for top-down design of a DRAM memory interface using a transformational approach. Sequential decomposition of the DRAM memory interface entails extraction of a DRAM memory object from a system description that incorporates the read/write protocol and accounts for refresh cycles. We apply sequential decomposition to a non-trivial example, a formally-derived realization of the Nqthm FM9001 microprocessor specification, called DDD-FM9001
