Reports are claiming that Micron is among the bidders.

A bid is in line with Micron’s habit of gaining share through acquisitions.

Additional gains could be the bigger upside.

As most readers must know by now, Toshiba (OTCPK:TOSBF) is seeking to sell a stake of up to 20% in its NAND business. Recent reports have named Micron as one of several bidders. Aside from owning a 20% stake in a profitable business, Micron (NASDAQ:MU) could gain share in the DRAM market by becoming the only DRAM supplier to Toshiba and maybe even Toshiba's partner in the NAND joint venture, Western Digital.

The NAND Business

Toshiba's NAND business has generated revenues of 845.6 billion yen ($7.4 billion) and operating profit of 110 billion yen ($0.96 billion) for the year ended in March 2016. Since then, the market conditions have improved, with NAND prices currently up around 25% on year. Toshiba's JV with Western Digital has about 35% market share in NAND, with slight variations from quarter to quarter, while Micron's share is slightly above 10%.

The DRAM and NAND markets are very sensitive to the supply and demand balance. With few participants in each market, any increase in bit output aimed at share gains has an immediate impact on pricing. That's why the big players rarely make any substantial attempts to gain share.

Micron has a long history of gaining share through acquisitions; Inotera, last year; Elpida a couple of years before that, and so on. It should come as no surprise that Micron is one of the bidders.

Selling some DRAM

By buying a stake in Toshiba's business and tightening the relationship with Western Digital, one of Micron's main goals must be to become the exclusive DRAM supplier, or at least the main DRAM supplier to Toshiba and Western Digital.

The main market would be in mobile where MCPs (multi-chip packages) are an increasing trend. To keep it simple, an MCP packages DRAM and NAND together.

The entire mobile market is very large and also includes discrete NAND and DRAM, not just MCPs. Micron sees the 2017 TAM at $31 billion. In the most recent four reported quarters, Micron's Mobile Business Unit had revenues of $2.8 billion. With a DRAM design win in Apple's iPhone 7 and firmer memory prices this year, Micron's Mobile Business Unit would likely generate close to $4 billion in revenue in calendar 2017, for low-teens market share.

As you can see in the slide above, the MCP market segment is sizable. Out of the total TAM of $12.6 billion, we estimate that around 47% of the TAM is DRAM. Today, Toshiba and Western Digital must purchase DRAM from one of the three suppliers - Samsung (OTC:SSNLF), Micron or Hynix (OTC:HXSCF).

By reaching a deal to supply DRAM to Toshiba and Western Digital, Micron would gain substantial market share in a sizable TAM.

There are additional markets where Toshiba and Micron would require MCPs or even discrete DRAM - IoT, embedded, TV boxes, wearables and more.


Micron's participation in the bidding process is not surprising at all and a win would be a unique opportunity that can enable large share gains in DRAM.

For Western Digital, having a special relationship with a DRAM supplier is convenient and can enable a closer collaboration in developing future products.
