Toshiba and SanDisk develop the 19 nm process manufacturing technology to realize the world's smallest, lowest cost flash memory products, SSD and memory cards are inexpensive

Toshiba and SanDisk have announced that they have developed a chip that adopts the world's most advanced 19 nm manufacturing process to realize world's smallest and lowest cost flash memory products.

The other day IntelBy adopting the 25 nm process, the high-speed SSD "320 series" which became 30% less expensive than in the pastWe announced that it will be possible to expect further lower price of products such as SSD and memory card by further miniaturization.

Toshiba: News Release (2011 - 04 - 21): Development of NAND Flash Memory Using State - of - the - Art Process

According to Toshiba's and SanDisk's press releases, the company has developed a technology that can manufacture world's smallest and lowest cost NAND flash memory by adopting the world's most advanced 19 nm manufacturing process.

This is realized with the cooperation of Toshiba which collaborates in the flash memory business and mass production of 64 Gb (8 GB) chip which can record 2 bits per cell from the second half of 2011. In addition, models that can record 3 bits per cell that will realize further capacity increase as mass production starts will also be available.

In addition, small-sized and large-capacity storage is said to be realized for built-in storage and removable storage devices used in mobile phones, tablet terminals, and other devices by 19 nm process manufacturing technology.

By the way, it is about how cost reduction is caused by advancing miniaturization of the manufacturing process, but generally, as the miniaturization of the manufacturing process progresses, it becomes the raw material of semiconductorsSilicon waferIn order to be able to make more semiconductor chips from 1 piece. There is also the merit that power consumption and heat generation can be suppressed by miniaturizing the chip itself.

In other words, the miniaturization of the manufacturing process has a very important meaning for semiconductor manufacturers, and at the same time, as manufacturing costs are reduced, users can get products at low cost.
