Distortion Control Technology

[Apoptosis]

Looks like Elpida has come up with some new techniques on improving yields for IC's on their DRAM. We all know that leakage is bad (Think Prescott) and hurts performance! Well turns out that Elpida is trying to reduce these leakage and have isolated the "leak" prone spots and have changed their method of manufacturing. Seems like common sense for a company to fix known issuses, but hey this is the memory industry.

The move is called Distortion Control Technology. As DRAM memory cell leakage current affects data retention, the ability to find and prevent the leakage will improve yields.

Imperfections that cause degradation of data happen during cell transistor production, and form in areas where there are distortions in the cell transistors due to stresses during manufacturing.

Researchers have isolated point defects, process artefacts and material impurities and has found a way to introduce conditions in manufacturing to stabilise and prevent these defects.

A heat process can control the internal stresses in materials during the manufacturing of DRAM, and give a two fold improvement in data retention in the memory chips.

Elpida will apply the design technology to its current and future memory products, it said. µ

So do all the makers have the same issue (ddr2)??

Every one pushing under about 10um is having this type of problem.
