Kioxia Develops New 3D Semicircular Flash Memory Cell Structure "Twin BiCS FLASH"

Kioxia Corporation today announced the development of the world's first three-dimensional (3D) semicircular split-gate flash memory cell structure "Twin BiCS FLASH" using specially designed semicircular Floating Gate (FG) cells. Twin BiCS FLASH achieves superior program slope and a larger program/erase window at a much smaller cell size compared to conventional circular Charge Trap (CT) cells. These attributes make this new cell design a promising candidate to surpass four bits per cell (QLC) for significantly higher memory density and fewer stacking layers. This technology was announced at the IEEE International Electron Devices Meeting (IEDM) held in San Francisco, CA on December 11th.

3D flash memory technology has achieved high bit density with low cost per bit by increasing the number of cell stacked layers as well as by implementing multilayer stack deposition and high aspect ratio etching. In recent years, as the number of cell layers exceeds 100, managing the trade-offs among etch profile control, size uniformity and productivity is becoming increasingly challenging. To overcome this problem, Kioxia developed a new semicircular cell design by splitting the gate electrode in the conventional circular cell to reduce cell size compared to the conventional circular cell, enabling higher-density memory at a lower number of cell layers.

Goke Microelectronics Launches Toshiba XL-Flash Based NVMe SSDs

As the industry's leading provider of SSD controllers and storage solutions, Goke Microelectronics was invited to the 2019 Flash Memory Summit to demonstrate an ultra-low latency NVMe SSD based on Toshiba Memory's XL-FLASH memory. One year ago, Toshiba Memory announced XL-FLASH at the 2018 Flash Memory Summit, promising to use ultra-low latency 3D SLC flash to reduce read latency to 5μs, which is equivalent to 1/10th of read latency of 3D TLC NAND.

Goke 2311-series drives are based on the 2311 SSD controller and are paired with Toshiba Memory's XL-FLASH memory. The prototype of 2311-series drives have implemented an overall 4K random read latency under 20μs and the final drives will offer a 4K random read latency in less than 15μs. Goke 2311-series drives support up to 4 TB capacity with a maximum write bandwidth of 1 GB/s and read bandwidth of 3 GB/s through a PCIe Gen 3 x4 interface. They will also support SM2/3/4 and SHA-256/AES-256 with built-in security engines.

Yangtze Memory Begins Mass-production of 64-layer 3D NAND Flash Memory

Yangtze Memory Technologies (YMTC), a Chinese state-backed semiconductor company founded in 2016 as part of the Chinese Government's tech-independence push, has commenced mass-production of 64-layer 3D NAND flash memory chips, at a rate of 100,000 to 150,000 wafers per month leading into 2020. The 64-layer 3D NAND chips are based on YMTC's "in-house" Xtracking architecture. The company is already developing a 128-layer 3D NAND flash chip, and is skipping 96-layer along the way.

YMTC's capacity will be augmented by a new fab being built by its parent company, Tsinghua Unigroup. Tsinghua is a state-owned company which holds a controlling 51 percent stake in YMTC, and is a beneficiary of China's National Semiconductor Industry Investment Fund. When it goes online in 2021-22, the new Tsinghua fab, located in Chengdu, will augment YMTC's capacity by an additional 100,000 12-inch wafers per month. Its existing fab in Nanjing will also receive a capacity expansion.

Toshiba Talks About 5-Bit-per-Cell (PLC) Flash Memory

Toshiba at the Flash Memory Summit announced they've managed to develop a 5-Bit-per-Cell memory solution Based on its BiCS 4 flash memory technologies, the feat was achieved using a modified module of Quad-Level Cell (QLC) memory. This shows the technology is not only feasible, but has room for improvement, since an adapted QLC technology will always be inferior to a natively-developed, Penta-Level Cell (PLC) solution.

To achieve this ability to store one extra bit of information per cell (compared to QLC), a new level of voltage refinement is required: the cell has to be able to change its state according to one of 32 voltage states, which, in turn, have to be read out correctly by the flash memory controller. This reduces the cell's performance and endurance (as does any increase in the number of bits per cell), and will require a number of solutions to mitigate and compensate for this reduced performance. However, density has become an increasing concern from manufacturers, hence the continued development of deeper, more variable voltage states that allow for even more information to be stored in the same silicon area. Higher density means cheaper solutions, but density increased in such a way has known trade-offs that have been much talked about ever since the transition from Single-Level Cell (SLC) up to the (nowadays ubiquitous) QLC.

NAND Flash Prices Could Reach $0.08/GB in 2019

Prices of NAND flash could drop to historic lows of $0.08 per gigabyte in 2019, according to Jim Handy from Objective Analysis, addressing delegates at the 2018 Flash Memory Summit. If you add the cost of the controller, optional DRAM chip, and other low-cost parts that make up an SSD, 480~512 GB drives under $70 could finally be a reality; followed by 1 TB under $120, and 2 TB under $200. Handy attributes the low prices to a catastrophic oversupply of NAND flash in the industry, which could push manufacturers to the brink of economic collapse.

The price drop is also accelerated with the introduction of the QLC (4 bits per cell) technology, which increases densities (and conversely decreases price/GB). Luckily, most NAND flash manufacturers also happen to make DRAM, and are offsetting some of their NAND flash losses with DRAM profits, as DRAM remains in undersupply. The NAND flash price-crash threatens to wipe out conventional hard-disk drives from the consumer-space, at least in matured markets; relegating them to developing markets.

SK Hynix Unveils 4D NAND Flash Memory Concept

3D NAND flash revolutionized flash storage as it used the third dimension (height) to stack multiple NAND flash layers, resulting in infinitesimally smaller footprint and reduced costs. SK Hynix believes that a "4-dimensional" NAND flash package is possible. Don't worry, such a stack doesn't look like a tesseract. Conventional 3D NAND flash relies on stacks of charge-trap flash (CTF) cells spatially located alongside its periphery block (which is responsible for wiring out each of the layers of the CTF stack). On a 2-D plane you'd be spending substrate real-estate on both the CTF and periphery block.

SK Hynix believes that the periphery block can be stacked along with the CTF stack, with microscopic vias wiring up the stack along the periphery, reducing the footprint of each cell stack. 4D stacking will also allow for greater number of CTF stacks per cell. Just to be clear, we're talking about stacks of cell and not stacks of NAND flash dies. The V5 cell-stack in SK Hynix's design entails 4 cells and periphery blocks sandwiched. The first implementation of this technology is a 96-layer 4D NAND flash chip with 512 Gb of capacity and TLC (3 bits per cell) density, although the technology is ready for QLC cells. This 512 Gb chip will begin sampling by the end of 2018, and the company is already working on a 1 Tb chip for 2019.
