ISSI's 256Mb DDR2 SDRAM uses a double-data-rate architecture to achieve high-speed operation. The double-data rate architecture is essentially a 4n-prefetch architecture, with an interface designed to transfer two data words per clock cycle at the I/O balls. The 256Mb DDR2 SDRAM is provided in a wide bus x32 format, designed to offer a smaller footprint and support compact designs.
