Samsung manufacturing leap to make cheaper, faster chips

Samsung revealed a chip making technique able to significantly increase the amount of data you can store in iPods, iPhones and other devices.

Samsung Electronics Co. has developed a chip-manufacturing technique able to significantly increase the amount of music, pictures, videos and other data people can store in future iPods, iPhones and other devices.

The world's largest memory chip maker showed off a 64G-bit multilevel cell (MLC) NAND flash memory chip made with an entirely new 30-nanometer production technology. A nanometer is a billionth of a meter, and the measure refers to the average size of the smallest features on the chip. The manufacturing breakthrough, which Samsung calls self-aligned double patterning technology (SaDPT), will enable the company to greatly increase the storage capacity of new NAND flash memory chips once the technology is in commercial production.

For example, 16 of the 64G-bit chips can be combined in a memory card for 128G bytes of storage space, enough for 80 DVD movies or 32,000 MP3 music files, the company said in a statement.

Even more important for users, Samsung was able to make the technology leap without requiring certain expensive new chip making equipment. While moves to smaller production technologies often require investment in expensive new photolithography equipment, the company was able to use current photolithography gear to etch circuits on the silicon wafers. That should ensure low production costs and reasonable prices for end-users.

SaDPT technology uses two pattern transfers to create the circuit design of each chip. The first transfer spaces the circuits widely apart, then the second transfer uses that space between the circuits to add another circuit, with the result that the circuitry is more densely packed together.

Samsung has applied for 30 patents related to the new 64G-bit flash chip, and said it also created a 32G-bit chip with the same production technology. The company expects to begin mass production of 64G-bit flash chips with its 30nm manufacturing technology in 2009.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
