eMMC/ eMCP - Samsung lose, Hynix gain $1.7Bil

The market of embedded flash controller grew from $6 to 9.5 Billion between 2012 to 2013 (see the article below). 

The article does not elaborate on the large increase of market share by Hynix and Toshiba. Hynix gain market share from 6.3% to 22.5% while Toshiba from 18.7% to 22.5%.

Wondering what is the cause for Hynix $1.68 Billion growth? It will be interesting to compare to the market share of the overall Flash NAND memory market shares. Is Apple behind Hynix growth?

Interesting to see today news that Quarterly Profits of Samsung Electronics Forecast to Drop
IT & Mobile Division, which accounted for over 60 percent of the electronics giant’s sales and business profits last year. The division’s smartphone and tablet PC shipments are estimated to have declined significantly in the current quarter. “According to our forecast, smartphone and tablet PC shipments have fallen at least 10 percent and approximately 20 percent from the preceding quarter, respectively,” said research analyst Song Myung-sup at HI Investment & Securities”

Recently, Gartner released a report, "Market Share Analysis: eMMC and eMCP Vendors by Revenue, Worldwide, 2013." The top ranked vendor for eMMC and eMCP market was Samsung Electronics, with 35.6% of worldwide revenue (around $3.317 billion). The top four vendors, Samsung, Toshiba, SK Hynix, and SanDisk, claimed 95.4% revenue share in 2013, up from 90% the previous year. Sales of eMCPs saw higher growth in 2013 than eMMCs. In the report, Gartner attributes this to the increased support of eMCPs by application vendors for low-cost smartphones.

Table: Vendor revenue for eMMCs and eMCPs, worldwide, 2012-2013 (millions of dollars).

Officially known as JESD84-B50: Embedded MultiMediaCard (e.MMC), Electrical Standard (5.0), eMMC memory is a JEDEC standard that is currently in version 5.0. As JEDEC defines it, eMMC is an embedded non-volatile memory system that includes flash memory as well as a flash memory controller. The aim of the standard is to simplify the application interface design and free up the host processor from some of the low-level flash memory management tasks. About two years ago, we saw the introduction of embedded multi-chip package (eMCP) memory, which is eMMC memory with an additional DRAM module, developed for low-cost smartphones in an effort to speed time to market.

Gartner's principal analyst, Brady Wang, compiled the report. He found it surprising that sales of eMCPs saw higher growth in 2013. He also noted that TLC (also known as 3-bits-per-cell) NAND solutions for both eMMC and eMCP will see high adoption in 2014, both in smartphones and tablets. This will address the market demands for high levels of storage space while lowering costs.
eMMC and eMCP memory includes controllers. Some vendors are using their in-house controllers to gain a competitive advantage. 

Wang says: Some NAND flash vendors, including SNKD, Toshiba and Samsung, still use in-house controllers. Since the geometry of NAND flash moves fast and also the configurations of NAND flash chips between vendors are slightly different, it's important to have a close relationship between controller vendors and chip vendors. That's one advantage of in-house controllers. The other advantage is the cost.

Despite the success stories, challenges remain for mobile memory, and Wang identifies speed and performance as the top ones, as mobile memory is challenged to meet the demands of high-performance processors. As a result, he expects universal flash storage (UFS) memory to see its initial adoption in the second half of 2014, but only in very high-end, flagship products to start.
The advantages of UFS memory (as compared to eMMC/eMCP memory) are better performance, higher capacity, better bandwidth, better IOPS, and optimized performance for multithreaded applications, according to Wang. UFS uses a serial interface (eMMC is a parallel interface) and asynchronous I/O (eMMC is synchronous I/O), enabling it to efficiently move data between the host processor and mass storage.

Wang notes that currently the cost and power consumption of UFS is higher than eMMC, so this will constrain its adoption. However, with the introduction of multi-core architectures that require high-performance memory, UFS is well positioned. “Although the power consumption of UFS is higher than eMMC, its energy efficiency is better,” says Wang. He expects to see UFS in high-end smartphones, tablets, and ultrabooks. eMMC will still be the best choice for mid-to-low cost mobile applications. Wang also points to SATA SSDs as competition for UFS in ultrabook applications. Finally, he notes that UFS is not backward compatible with eMMC, which will slow its adoption in applications where eMMC is already used.
