With companies consolidating their product portfolios, it is good to see that most of them are cutting their losses. Hope for a good year for ST.

Wondering About Competing Toshiba 15 nm technology

Toshiba is saying they will be making 15nm chips.
http://www.businesswire.com/news/home/20140422006898/en/Toshiba-Starts-Mass- Production-Worlds-15nm-NAND#.U1zyeeY5TKw

Toshiba has achieved the world's smallest class chip size with the 15 nm process plus improved peripheral circuitry technology. The new chips achieve the same write speed as chips formed with second generation 19 nm process technology, but boost the data transfer rate to 533 megabits a second, 1.3 times faster, by employing a high speed interface.

Toshiba is now applying the 15nm process technology tp 3-bit-per-cell chips, and aims to start mass production in the first quarter of this fiscal year. The company will develop controllers for embedded NAND flash memory in parallel and introduce 3-bit-per-cell products for smartphones and tablets, and will subsequently extend application to notebook PCs by developing a controller compliant with solid state drives (SSD).

How are they doing this? What are the implications for ST?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
