Datech 2048MB PC6400 DDR2 Memory
The Datech DDR2-800 is a standard 240-pin DDR2 module with a working voltage of 1.8V. It is delivered in 1GB and 2GB models conforming to the JEDEC (Joint Electronic Device Engineering Council) standards. By using the leading-edge 0.70μm process and FBGA packaged DDR2 die, Datech has reduced the spherical contacts between the IC die and baseboard and so effectively lowered the die temperature and data noise while working at high frequency.

What's New with DDR2
DDR2 memory was developed by JEDEC, the memory industry's standards organization of which Kingston is a member company. DDR2 memory chips and modules use a naming convention similar to that used for the current DDR memory modules, but are not backward compatible due to incompatible module connections (number of pins), voltage and DRAM technology. DDR2 memory modules have a different key or notch than the same-sized DDR modules to prevent their insertion into an incompatible memory socket.
DDR2 memory chips will be available in Fine-pitch BGA (FBGA) chip packages for improved electrical and thermal characteristics. In addition, DDR2 memory chips will incorporate On-Die Termination (ODT) to minimize memory signal reflections at high speeds, thereby improving timing margins. DDR2 memory chips will come in capacities up to 4 Gigabits, allowing for higher-capacity modules |
