Why your RAM is more expensive - DRAM chip pricing more than doubled

As you may have noticed, the pricing of both DDR4 memory modules and NAND flash memory devices have gotten a lot more expensive over the last year or so. We're not going to talk about solid state storage in this article but we're going to zoom in on the DRAM market.

There's a new report from IC Insights that clearly illustrates why your RAM got so much more expensive. Last summer oversupply resulted in record low pricing but in the months thereafter a 180 degrees flip pushed the market deep into undersupply territory.

A variety of issues, like trouble with switching to smaller nodes, turned DRAM into a seller's market and this fueled the profits of large memory makers like Micron, Samsung and SK Hynix. The IC Insights report reveals that between July 2016 and July 2017, the average selling price of DRAM chips soared a massive 111 percent!

Historically, the DRAM market has been the most volatile of the major IC product segments. Figure 1 reinforces that statement by showing that the average selling price (ASP) for DRAM has more than doubled in just one year. In fact, the September Update to The McClean Report will discuss IC Insights’ forecast that the 2017 price per bit of DRAM will register a greater than 40% jump, its largest annual increase ever!

Just one year ago, DRAM buyers took full advantage of the oversupply (excess capacity) portion of the cycle and negotiated the lowest price possible with the DRAM manufacturers, regardless of whether the DRAM suppliers lost money on the deal. Now, with tight capacity in the market, DRAM suppliers are getting their “payback” and charging whatever the market will bear, regardless of whether the price increases hurt the users’ electronic system sales or causes it to lose money.

The three remaining major DRAM suppliers—Samsung, SK Hynix, and Micron—are each currently enjoying record profits from their memory sales. For example, Micron reported net income of $1.65 billion on $5.57 billion in sales—a 30% profit margin—in its fiscal 3Q17 (ending in May 2017). In contrast, the company lost $170 million in its fiscal 4Q16 (ending August 2016). A similar turnaround has occurred at SK Hynix. In 2Q17, SK Hynix had a net profit of $2.19 billion on sales of $5.94 billion—a 37% profit margin. In contrast, SK Hynix had a net profit of only $246 million on $3.39 billion in sales one year ago in 2Q16.

Previously, when DRAM capacity was tight and suppliers were enjoying record profits, one or more suppliers eventually would break rank and begin adding additional DRAM capacity to capture additional sales and marketshare. At that time, there were six, eight, or a dozen DRAM suppliers. If the supplier was equipping an existing fab shell, new capacity could be brought on-line relatively quickly (i.e., six months). A greenfield wafer fab—one constructed on a new site—took about two years to reach high-volume production. Will the same situation play out with only three DRAM suppliers left to serve the market?

Recently, Micron stated that it does not intend to add DRAM wafer capacity in the foreseeable future. Instead, it will attempt to increase its DRAM output by reducing feature size that, in turn, reduces die size. Eventually, as the company moves down the learning curve, it will be able to ship an increasing number of good die per wafer. However, SK Hynix, in its 2Q17 financial analyst conference call, stated that it plans to begin adding DRAM wafer capacity since it is not able to meet increasing demand by technology advancements alone. Samsung has been less forthcoming in its plans for future DRAM production capacity.

Although Samsung and Micron may tolerate SK Hynix’s DRAM expansion efforts for a short while, IC Insights believes that both companies will eventually step up and add DRAM wafer start capacity to protect their marketshare—and DRAM ASPs will begin to fall. As the old saying goes, it only takes two companies to engage in a price war—and there are still three major DRAM suppliers left.
