You couldn't finish off Heinx, and now you don't have the guts to raise the contract price. Overall, I'm not really impressed. So, if you don't mind, we will. Let's discuss on the phone. Let me know when and where, and I'll look into it. Give Lynn more money. He has boosted DRAM prices across the US and the world on his own. A bad player can keep the DRAM business on thin ice.

These remarks show how memory makers worked together to purposefully limit output and keep costs high for customers. Later investigations described the operation as one of the largest cartels ever found.

Charges and an investigation by the Government

Finding and punishing people who commit cartel crimes became the antitrust division's top goal. Authorities said they would take action against companies that were involved in fixing DRAM prices illegally.

Samsung Electronics Company and its subsidiary, Samsung Semiconductor, pleaded guilty and agreed to pay a $300 million fine for participating in a DRAM chip price-fixing conspiracy. DRAM is a semiconductor memory chip widely used and generating billions in sales.

Samsung was the third semiconductor company to admit culpability. Hynix Semiconductor and Infineon Technologies both admitted guilt and paid fines of $185 million and $160 million, respectively.

Industry-Wide Collusion

At least fifteen companies in the DRAM business were involved in the scheme. More than 117 people worked at the five biggest manufacturers. Some people kept their jobs after the cartel fell apart, while others moved into higher-level positions.

Every week, the cartel shared price information and worked together to reduce supply. Price floors were set up in a coordinated way, auctions were rigged, and prices went up. Manufacturers used fake demand statistics to explain why prices went up.

Participants also tried to hide their communications and established groups within the cartel to get rid of weaker individuals. Eventually, the probe brought the operation to an end.

Authorities accused Samsung of working with Hynix, Infineon, and other partners to set the price of DRAM delivered to computer and server makers.

What this Means for Computer Makers and Users

The plot made companies that depended on DRAM have to deal with higher costs. Dell and Apple said computer costs had to rise because DRAM prices had risen. Other companies kept costs the same but cut back on the amount of memory that came with their systems. Some businesses put out PCs with less memory than older models at the same price.

These actions showed how DRAM prices affect the rest of the IT industry and made it clear that antitrust laws need to be enforced in high-tech industries.

How the Memory Industry Works

Micron, Samsung, and SK Hynix are the three biggest companies in the memory market today. Most of the world's DRAM production is done by these companies.

Over the course of decades, the three businesses became the most powerful as smaller manufacturers were bought out and competition drove them out of business. The fact that modern semiconductor production factories are so big also made the business more concentrated. It costs billions of dollars to build and equip facilities, making it hard for new competitors to enter.

To keep production running smoothly and reduce downtime, modern fabrication factories use automated carrier systems to shuttle silicon wafers between equipment.

Technology for Early Memory

Long before semiconductor DRAM, there were memory technologies. Some early memory systems were handcrafted. In core rope memory, a wire going through a core stood for a one, and a wire going around a core stood for a zero.

It may take months to weave, and fixing mistakes took a lot of handwork. One example of this technology was employed in systems made for expeditions to the moon. The procedure was slow and labor-intensive, but it worked well for early computers.

Making Memory Chips Work

As semiconductor technology improved, dynamic random access memory became a new way to store data. DRAM made it possible to store data in small cells made of transistors, which were cheaper and denser than those of older technologies.

Engineers found that making transistors smaller had several benefits. Smaller devices worked faster, used less power, and could hold more data. People were initially doubtful that transistor sizes could be reduced beyond certain limits. Still, technology kept improving, increasing memory capacity.

The DRAM Market is Growing

Several companies entered the DRAM business in its early years. Texas Instruments, Motorola, AMD, and other companies made memory chips for computers.

As computers became increasingly widespread, the need for memory grew quickly. The amount of data that DRAM chips could hold grew quickly, from small kilobit chips to much bigger ones.

The expansion of the business also brought in manufacturers from outside the original production areas. Government-backed research initiatives and manufacturing investments accelerated technological growth.

Trade problems, Accusations of Dumping, and Competition

Because of competition in the memory industry, there were many charges of dumping. Companies said their rivals were selling memory chips for less than it cost to make them to gain more market share.

Manufacturers lodged complaints with the government over unfair pricing. In certain situations, governments investigated these accusations and imposedimposed duties on semiconductor devices imported from other countries.

Limiting semiconductor exports made them harder to obtain, driving up the price of memory. Computer makers and other businesses that depend on memory components were hurt by rising prices.

New Competitors are Coming in

In the years that followed, other companies started making DRAM. Companies invest heavily in building factories and expanding manufacturing capacity. Sometimes, other industries were also affected by memory shortages. Because there weren't enough chips, video game companies put off releasing new games or made their libraries smaller. Computer makers also had trouble getting enough DRAM and SRAM parts.

While consolidation made it harder for firms to compete, the sector continued to grow.

The End of the Cartel and What Happened in Court

The investigation into price manipulation started in 2002. Micron asked the government for mercy and provided information about the cartel. In the end, the government punished Samsung, SK Hynix, Infineon, and other corporations a total of $731 million for price rigging between 1998 and 2002. In 2004, US sales of DRAM alone totaled about $7.7 billion.

People who were part of the scheme received prison sentences ranging from 4 months to 14 months. Some workers were penalized, while others were put under home arrest.

Promotions and what Happened in the Industry After

Even though several people were found guilty, many who took part kept their jobs and ultimately received promotions. Some of the executives involved in the controversy went on to hold high-level positions in their firms.

For instance, a Samsung sales manager who was implicated in the case ultimately became the president and CEO of Samsung Europe. Other companies involved in the investigation also experienced similar career growth. These events show that large companies can handle the cost of fines.

Consolidation of the Market

Over time, the number of major DRAM makers has decreased significantly. The top three corporations had around 35% of the market in the 1990s. The top three controlled almost 95% by 2022.

NEC, Toshiba, and Hitachi were some of the first companies to lose market share as consolidation continued. The same companies implicated in the price-fixing affair remain the most powerful. The fewer competitors there were, the more power the biggest firms had over decisions about prices and production.

The Beginning of the Modern Memory Industry

Memory technology predates modern computers. It goes back to older parts like vacuum tubes and magnetic core memory. In the past, computers needed thousands of vacuum tubes to work.

For many applications, magnetic core memory replaced vacuum tubes. Core memory used tiny magnetic rings to store binary information based on the orientation of their magnets. Core memory was better than older technologies, but it had to be assembled by hand and was limited in size.

Switch to Modern Semiconductor Memory

As semiconductor manufacturing improved, DRAM replaced magnetic core memory. Semiconductor memory made it possible to store more data, do things faster, and do so at lower cost.

Manufacturers built more factories and improved the methods for making things. Transistor scaling enabled rapid increases in memory capacity while lowering the cost per bit. The DRAM industry grew along with the semiconductor industry as a whole. It became an important part of modern computer systems.

Final Thoughts

The DRAM market remains highly concentrated today. To make anything, you need complex fabrication plants, specialized equipment, and a lot of money.

Because of this, only a few businesses make a lot of DRAM. Over the years, mergers and acquisitions have changed the way the memory market operates today. The structure of the business today makes more sense when you know about the history of DRAM development, competition, and price fixing.
