AVR200412 DDR2 SDRAM

The 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. A single read or write access for the DDR2 SDRAM e.
