Samsung Electronics has developed a thin, low-power 1GB chip for portable devices such as cameras, media players and game consoles.

The 1GB Mobile DRAM (dynamic random access memory) chip, which the South Korean manufacturer claims is an industry first using 80 nanometer process technology, will start shipping in the second quarter of 2007, the company said today.

The chip has a new temperature-sensing feature that maximizes the self-refresh cycle to reduce power drain in standby mode by 30 percent over conventional memory chip designs, according to Samsung.

In addition, the chip is at least 20 percent thinner than a multi-stack package of 512MB dies, enabling a single high-density package system of 1.5GB or even 2GB Mobile DRAM memory, the company said.

The new Samsung chip can also be combined with Flash memory via package-on-package designs.
