The memory clock speed of the industrial DDR2 SDRAM was reduced by half compared to the DDR1 generation for a given bus speed. This change resulted in higher bus speed for an equivalent memory clock rate at the cost of increased latency. The operating voltage was reduced from 2.5 Volts to 1.8 volts to reduce power consumption.
DDR2 DIMM modules are available in a variety of form factors including 240 pin full-sized DIMM, 200 pin So-DIMM, 240 pin Very Low Profile (VLP) DIMM, 244 pin Mini-DIMMs, and 240 pin FB-DIMMs. These form factors are not interchangeable with DDR or DDR3 form factors.
