DDR2 Module Portfolio
Frequency/CAS latency
• DDR2-400 @ CL = 3
• DDR2-533 @ CL = 4
• DDR2-677 @ CL = 5
• DDR2-800 @ CL = 5
• DDR2-800 @ CL = 6
DDR2 quickly became the technology of choice for performance PC’s & servers with speeds up to
800Mhz. DDR2 continues to be a major percentage of total DRAM output, being used in multiple
applications and markets. DDR2 has the ability to operate the external data bus at twice the rate
of DDR by improved bus signaling and by operating the memory cells at half the clock rate. Other
advantages are lower power consumption, lower heat generation and higher density compared to
DDR.
