ISSCC 2015 -Latest Circuits Innovations

Below are some highlights from 2015 " International Solid-State CircuitsConference once again served up a smorgasbord of silicon innovations."

It is interesting that while Samsung is continuing to develop 3D devices and processing on a single chip -

"Samsung described a second generation of its 128 Gbit 3-D NAND flash, a 3-bit/cell version with 32 layers now in production on a 68.9mm2 die. The Korean giant is ahead of the pack in dense flash and also is expected to beat TSMC to market with 14/16nm FinFET logic later this year, a fact that help it retain archrival Apple as a foundry customer."

ITRS and Intel focus on developing chip stacks - 

"Paolo Gargini who leads the ITRS semiconductor road map effort said chip stacks are today what high-K metal gate design was in 2007, the next big requirement for progress.

Intel fellow Mark Bohr disagreed. “We need vertical interconnects one or two orders of magnitude more dense than today’s through-silicon vias,” he said"

Apple Ask Samsung for iPhone 6 Parts

The flash memory bug of TLC performance versus MLC leads Apple to fix the memory IC controller and move from MLC to TLC NAND. It takes about a year to implement such changes. In the meantime, Apple looks to Samsung to provide MLC NAND (see the article below).



This is just another example of the limitations that the consolidation of semiconductor fabrication companies cause on their customers such as Apple. More about semiconductor industry consolidation from March 2012 Moore's Law Slowwwing and from February 2013 Semiconductor Moore's Law Running out of Money.

Samsung to Provide Parts for Apple’s iPhone 6 and 6 Plus in Order to Fix Huge Bug

Samsung to Provide Parts for Apples iPhone 6 and 6 Plus in Order to Fix Huge Bug Apple iPhone 6 and iPhone 6 Plus 300x225Samsung and Apple have been at war with each other for a long time due to a legal issue where the American tech giant sued Samsung for copying its iPad design. The trial turned out well in the end for Samsung, who continued to heavily criticize Apple and taunt the iPhone 6 and the iPhone 6 Plus devices in their promos and video adverts.
Taking this into consideration, it comes off as a huge and ironic surprise that the South Korean tech company will be providing parts to Apple. Apparently, there have been some discussions between the two tech companies in order to obtain NAND flash memory chips, as Apple needs some supplies of the triple-level cell NAND flash used in the iPhone 6.
Samsung to Provide Parts for Apples iPhone 6 and 6 Plus in Order to Fix Huge Bug Samsung Apple iPhone 6 and iPhone 6 Plus 300x200The higher capacity iPhone 6 handsets are apparently experiencing constant crashes and reboots, and apparently it’s because of the TLC memory. Naturally, Apple has to fix affected devices as soon as possible, especially when you think about how much money people spend on them. Apple’s products have some of the steepest price tags in the tech industry, but the quality has been heavily degrading over the years, making it look like Apple has no quality control. Besides supplying parts for Apple, Samsung will be making batteries for the iPhone 6 as well, according to Business Korea. This has been happening for a while, but Apple has been trying to reduce its reliance on Samsung components for its devices.
It seems that the two companies are going to bury the hatchet, but this could be strictly business-related, so we’ll have to wait and see.

Toshiba, SanDisk 15nm MLC/TLC NAND

Partners Toshiba and SanDisk have developed 15-nanometer process technology for NAND flash memory...will replace the second-generation 19-nm process technology when production begins at Toshiba’s plant in Yokkaichi, Japan, Toshiba said

Toshiba, SanDisk start mass production of 15nm NAND memory

Anton Shilov

Toshiba Corp. and SanDisk Corp. on Wednesday said that they would start to produce multi-level cell (MLC) NAND flash memory using 15nm fabrication process later in April. The new manufacturing technology allows Toshiba to make world’s smallest and potentially cost-efficient 128Gb NAND flash memory.
Initially, Toshiba and SanDisk will produce 128Gb MLC (two-bits-per-cell) MLC NAND flash memory using the 15nm process technology at Fab 5 phase one, where the fabrication tech will replace the companies’ second-gen 19nm manufacturing process. The phase stage of Fab 5 is currently under construction, and the new technology will also be deployed there.
The new 128Gb MLC NAND flash chips achieve the same write speed as chips formed with second generation 19nm process technology, but boost the data transfer rate to 533Mb/s, 30 per cent faster, by employing a higher speed interface.
Toshiba claims that it had achieved the world’s smallest class chip size with the 15nm process and improved peripheral circuitry technology.

According to SanDisk, the 15nm technology uses numerous progressive process innovations and cell-design solutions to scale the chips along both axes. SanDisk’s All-Bit-Line (ABL) architecture, which contains proprietary programming algorithms and multi-level data storage management schemes, has been implemented in the 1Z technology to deliver NAND flash solutions with no sacrifice in memory performance or reliability. SanDisk’s 1Z technology will be utilized across its broad range of solutions, from removable cards to enterprise SSDs.
Separately, Toshiba announced that it would use the 15nm fabrication process to produce triple-level-cell (TLC, three-bits-per-cell, 3bpc) NAND flash memory. Such memory, provided that the yields are sufficient, will be the world’s most cost-efficient NAND flash. The company aims to start mass production of TLC NAND using 15nm process in June, 2014.
The company intends to develop controllers for 3bpc embedded NAND flash memory in parallel and introduce TLC NAND products for smartphones and tablets. Eventually Toshiba will use 15nm TLC NAND with special controllers for solid-state drives.
Toshiba and SanDisk run joint NAND flash manufacturing operations in Japan.

KitGuru Says: If Toshiba and SanDisk manage to sustain 3000 write/erase cycles with 15nm MLC NAND (typical amount of cycles sustained by modern MLC), then the new memory type will enable lower-cost SSDs already this year. In case the new type of memory (like 15nm TLC NAND) requires new controllers, then its adoption will take time.

Where is DRAM Innovation?












The article, Hynix 30 nm DRAM layout, process integration adapt to change ,  discusses advances in DRAM memory at Hynix. DRAM memory has not been able to shrink the memory cell as quickly as flash memory. Leading edge flash memory products with dimensions around 20nm or less are being introduced to production, while DRAM memory is still above 30nm (see figure 4 in the article below).


While flash memory has a key advantage of keeping the information even without power, there is still a place for DRAM memory. Many of the process technology advances are being implemented at a slower rate in DRAM production. However major memory cell and circuit improvements are not being pursued. For example, storing multiple bites in one physical flash memory cell has been done for several years. There are 3-bit-per-cell (TLC) NAND and 2-bit-per-cell (MLC) flash available in the market, but there is no DRAM product with multiple bits in the same cell.
