Samsung has started mass-producing new 250GB SSDs that feature 100-layer V-NAND. It is the first time in the industry that such a V-NAND memory chip is made, according to the company. In recent years, the number of layers has been increased time and again to get more capacity in a single chip.

The new 256Gb 3-bit V-NAND is used to produce SSDs for enterprise PCs, writes ZDNet. The new SSDs are therefore delivered to a global computer manufacturer, although Samsung did not say who that manufacturer is.

Improved performance

Samsung has developed a unique channel hole etching technology. This allows approximately 40 percent more cells to be added than in the previous 9x-layer single-stack structure. The South Korean tech giant also managed to add a speed-optimised circuit, which enabled it to achieve faster read and write speeds.

This involves a writing speed of 450 microseconds and a reading speed of 45 microseconds. This represents a 10 percent improvement in performance compared to the older ninety-layer V-NANDs. Energy consumption has fallen by 15 percent.

The production steps and chip sizes have also decreased. As a result, the production rate must be increased by 20%.

Deployment of V-NAND

Besides the introduction of the new 250 GB SSD, Samsung also plans to offer 512 3-bit V-NAND SSD and eUFS in the second half of this year. In addition, the production of the sixth generation of V-NAND solutions should be expanded from next year. This production takes place at the Pyeongtaek campus in South Korea. With the increased production, the company wants to be able to respond better to the increased worldwide demand for chip sets from its customers.

The tech giant also plans to use the new V-NANDs later for mobile and automotive applications, in order to further strengthen his leadership position.

Fastest flash storage

Samsung said earlier this year that it had begun mass-producing the fastest flash storage ever. That’s the 512 GB eUFS 3.0, which must be twenty times faster than a typical microSD card.

The chip comes with a higher reading speed of 2,100 MB per second and a writing speed of 410 MB per second. The chips are made from eight stacks of 512-gigabit V-NAND and one controller.
