This year’s DRAM memory, NAND flash memory prices to save the company Micron, they formally acquired the company on Monday, China Branch, the memory business even more powerful, and flash memory, Micron has also announced two good news – the company’s 3D NAND flash memory capacity Has more than 2D NAND flash memory, the cost of the first generation of 3D NAND flash memory in line with expectations, the stack layer to 64 layers of second-generation 3D NAND flash memory is on the road, the end of this year will mass production.

For 3D NAND flash, we are no strangers, and now the market is turning to a lot of SSD 3D NAND flash memory, whether performance or capacity or write life, 3D NAND flash memory than traditional 2D NAND flash memory is much better, manufacturers will Thereby reducing costs and increasing production. To Micron, for example, their 2D NAND flash memory is the main 16nm process, MLC / TLC flash memory core capacity, but 128Gb, ​​while the 3D NAND technology MLC flash core capacity has 256Gb, TLC is to 384Gb, much higher than the 2D NAND Flash memory. ms3348-8-10

In turn, 3D NAND, the strongest Samsung runs fastest, Toshiba / flash Di, SK Hynix followed, Intel and Micron is relatively slow, but once the 3D NAND flash memory production, due to capacity congenital Advantage, more than 2D NAND flash memory capacity is a matter of time. Micron CFO Ernie Maddock at the Barclays Bank Global Technology, Media and Communications Conference to confirm that the company’s 3D NAND flash memory capacity and 2D NAND flash memory has come to the inflection point, that is 3D flash memory capacity (in bit capacity) More than 2D NAND flash.

Ernie Maddock also mentioned that their first generation of 3D NAND flash memory has achieved the desired goal of reducing costs, after Micron pointed out in the first half of this year’s road map 3D NAND flash than 2D NAND at least 20% lower cost, has now achieved 20 -25% of the cost reduction. ms-470n

For Micron, the good thing is more than this one, their second-generation 3D NAND flash memory to mass production, earlier Micron announced that the second generation of 3D NAND this summer in Singapore Fab 10X factory production, compared to The current 32-layer stack, the second generation of 3D NAND flash stack layer to 64 layers, capacity to further improve the cost will be further reduced by 30%.
