The DDR2 SDRAM uses a double data rate architecture to achieve high-speed
operation. The architecture is essentially a 4n- prefetch architecture.A
single read or write access for DDR2 SDRAM effectively consists
of a single 4n-bit-wide, data transfer at the internal DRAM core
and four corresponding n-bit-wide, then data transfer at the I/O
pins ....
