Toshiba Launches NVMe Client SSD Utilizing 64-Layer 3D Flash Memory
Published2017.08.04 14:53Toshiba Memory Corporation has launched a single-package NVMe client SSD utilizing 64-layer 3D flash memory
Toshiba Memory Corporation, a global leader in memory solutions, today announced the launch of its new BG3 series of single-package NVM Express (NVMe™) client SSDs that integrate its cutting-edge 64-layer 3-bit-per-cell (TLC) BiCS flash memory and ball grid array (BGA) package controller. Toshiba Memory Corporation has begun sample shipments to PC OEM customers in limited quantities today, with plans to gradually increase shipment volumes starting in the fourth quarter of this year.
The new BG3 series SSD leverages PCI EXPRESS (PCIe) Gen3 x 2 lane and NVMe revision 1.2.1 architecture features. The BG3 series SSD is also equipped with Host Memory Buffer (HMB) functionality, using host memory as a substitute for DRAM to support developers of small form factor devices that need to achieve a balance between power savings and space efficiency while maintaining high performance and low power consumption. Additionally, the combined advantages of SLC cache functionality, enhanced flash management, and flash memory performance deliver performance up to 1,520 MB/s for sequential reads and up to 840 MB/s for sequential writes.
The new BG3 series will be available in three storage capacities: 128GB, 256GB, and 512GB. Each capacity conforms to the industry's smallest class SSD form factors—a surface-mount 16mm x 20mm x 1.5mm single-package M.2 1620 and removable M.2 2230 modules. The BG3 series includes 128GB and 256GB single-package models conforming to M.2 1620-S2 with 1.35mm thickness and 512GB single-package models conforming to M.2 1620-S3 with 1.5mm thickness, making them smaller than previous generation products. This will contribute to enabling new design development for advanced mobile and embedded devices, including thin mobile PCs and tablets. Furthermore, the BG3 SSD can be applied to power and space-saving server boot storage in data centers due to its small size and low power consumption.
Security requirements are addressed by offering self-encrypting drive (SED) models that support TCG Opal version 2.01.

China's Shift from DRAM to NAND: Can Korea's 3D NAND Compete?
As the semiconductor market boom continues, Gartner, an IT market research firm, stated in a report on the 14th that "market growth is expected to continue through next year due to price increases and production volume growth in DRAM and NAND flash memory." IHS Markit senior research analyst Len Jelinek forecasted that "due to the large-capacity trend in IT devices, the amount of memory semiconductors installed in devices is increasing, and the memory semiconductor market growth rate will reach 30.3% this year." The system semiconductor market is expected to grow 10.5% year-over-year, and microcontroller units (MCU) are anticipated to show 6.7% growth driven by autonomous vehicle development. The overall memory market is projected to show growth through 2018, but from 2019 onwards, it is expected to slow due to variables such as China's government semiconductor industry policies. Mirae Asset Daewoo analyst Do Hyun-woo anticipated that the 2017 semiconductor equipment market will continue following last year's growth, with DRAM, foundry, and backend processes leading to overall 6% growth. The DRAM equipment market saw investment decrease at 23% last year, but this year investment is expected to increase by 15%, and due to memory market influence, investment will concentrate particularly in the second half. As Samsung Electronics and SK Hynix increase production volume of 18nm DRAM and invest in 17nm DRAM, equipment demand is predicted to increase. The NAND equipment market is expected to decline 4-5% compared to last year, as concentrated new capacity investments from Samsung Electronics, Toshiba, and Micron occurred in 2016. Samsung Electronics in particular invested heavily in 3D NAND flash at its Pyeongtaek plant last year, with plans to mass-produce 64-layer 3D NAND in the first half of this year. SK Hynix is preparing M14 3D NAND flash on the second floor of its Icheon plant this year, with plans to mass-produce 72-layer 3D NAND in the second half.
