Increasing Flash Storage In Smaller Form Factor

Increasing Flash Storage In Smaller Form Factor, Is The General Trend

Increasing Flash Storage In Smaller Form Factor

From magnetic disks to solid storage we have developed many efficient storage products. Today the people are opting for faster and large capacity storage devices. Is that true?

Let’s take a look at some of these devices with Mr. Vivian Singh, CEO, Strontium Technology India Pvt Ltd.

We saw a jump of few gigabyte storage to recent 200GB within the 11mm×15mm×1mm form factor of microSD card. We are now at the mature stage of 14nanometer (nm) semiconductor device lithographic fabrication node.

The most-dense process for creating silicon flash memory cells to store data on planar NAND is between 10 nanometre (nm) and 19nm in size. To give some idea of how small that is, a nanometre is one-billionth of a meter – a human hair is 3,000 times thicker than NAND flash made with 25nm process technology. There are 25 million nanometres in an inch.It would not be a surprise to see the capacity flip and performance scooted in the near future.With this current scenario, we foresee requirement for low capacity legacy cards still persists. While uptrend seeking for huge capacity card demand is there but its unamusing as the hardware (host) which can support SDXC card is limited or undergoing the compatibility tuning stage.

With flash technology advancement from the beginning of SLC, MLC to TLC and now 3D NAND, greater capacity flash storage would be a norm in the near future to come.
