There’s been a lot of speculation and analysis on why Samsung would acquire SanDisk. Here’s my take.
1. Samsung needs the capacity. – Samsung has enough capacity, especially in this market.
2. Samsung is attracted by SanDisk’s retail reach. – Samsung has a strong retail brand and could have leveraged its own retail channels to push flash cards through its distribution network if it wanted to. Why do it now?
3. Samsung saves on royalty fees and the savings justify an acquisition. – Pay $3 billion (SNDK’s market cap) to save on $400 million a year? Sounds pretty good. >10% ROI. But the level of that royalty stream is not guaranteed and I don’t think Samsung would do a deal just to save on royalty payments.
4. Samsung wants the IP. – Sometime in the next few years, FG NAND flash is likely to hit a brick wall and an alternative technology will be required. CTF has its problems and one of the potential options is 3D memory (see http://forward-insights.blogspot.com/2008/06/sandisk-and-toshiba-to-jointly-develop.html). SanDisk appears to have some fundamental IP in that area. Sure, Samsung could negotiate an extension to their existing cross licensing agreement with SanDisk to include 3D memory but they don’t get the knowhow. The knowhow is what is going to allow the leaders to scale the brick wall.
Samsung is not known for big acquisitions and its last big acquisition of AST Research 20 years ago is not considered a success. And it’s hard to imagine SanDisk’s manufacturing and joint development partner, Toshiba standing idly by as Samsung takes ownership of SanDisk’s most prized assets.

SanDisk and Toshiba to Jointly Develop 3D Memory
In a SEC filing today, SanDisk disclosed that it had signed a collaboration agreement with Toshiba for re-writeable 3D memory. Both companies will cross-license related IP to each other and SanDisk will receive licensing payments from Toshiba.
Investment for SanDisk-owned equipment which includes tooling for 3D R/W and 3D OTP memory is forecast to amount to $400 million in 2009 and $200 million in 2010.
The 3D R/W memory which consists of stacked vertical diode arrays shares most of the process modules and design architecture concepts with the 3D OTP memory. In the case of 3D OTP memory, four layers of stacked memory cells are in volume production at the 80nm node with 45nm currently under development.
A four level 3D R/W memory will have to at least catch up with NAND flash on process technology to be considered competitive with x4 NAND flash. This would put 3D R/W memory at least 3-4 years out. The other issue is whether an eight level stack is manufacturable at high yields. An eight-level stack was demonstrated by Matrix in 2003 on a much less advanced 0.25um geometry. Producing eight level memory stacks at leading edge technology is another matter.
