DOJ DRAM price-fixing cartel — 2004–2007 pleas

Conspiracy period: April 1, 1999 – June 15, 2002 (per DOJ charging documents). Plea period: October 2004 – 2006. Aggregate fines (as of Oct 13, 2005 DOJ release): $646 million from three companies + five individuals. Additional pleas through 2006 brought the cumulative total above $700M.

Why it matters: The cartel case is the historical floor under everything in the modern memory market. It is also the answer to the question "if producers are restrained now, why did they collude then?" The 1995–96 crash left chronic overcapacity, and the surviving producers responded by behaviorally coordinating (price-fixing) rather than structurally coordinating (capex discipline). DOJ broke the behavioral coordination. The producers responded by adopting the structural version — which is what the present cycle's "discipline" framing represents.

The defendants and fines

Plea date Defendant Fine Notes
Oct 2004 Infineon Technologies AG $160M First plea
Dec 2004 4 Infineon executives $250K each Prison 4–6 months; 3 of 4 German citizens
May 2005 Hynix Semiconductor $185M
Oct 13, 2005 Samsung Electronics + Samsung Semiconductor (US) $300M "Second largest criminal antitrust fine in U.S. history" per DOJ release; "largest criminal fine since 1999"
Jan 2006 Elpida Memory $84M
2003 Alfred P. Censullo (Micron Regional Sales Manager) — Obstruction of justice; 6 months home detention; admitted withholding and altering documents in response to June 2002 grand jury subpoena served on Micron

Important clarification: A widely-circulated figure of "Samsung $730M fine" is incorrect. Samsung's individual fine was $300 million. The DOJ Oct 13, 2005 release notes that the cumulative total to that date — three companies and five individuals — was "more than $646 million." The often-cited $731M aggregate figure includes the subsequent January 2006 Elpida plea ($84M) and additional executive penalties.

What the conspiracy did

From the DOJ Samsung press release (Oct 13, 2005), verbatim:

"From April 1, 1999 to June 15, 2002, Samsung and its U.S. subsidiary, Samsung Semiconductor Inc., conspired with other DRAM manufacturers to fix the prices of DRAM sold to certain computer and server manufacturers. The computer makers directly affected by the price-fixing conspiracy were: Dell Inc., Compaq Computer Corporation, Hewlett-Packard Company, Apple Computer Inc., International Business Machines Corporation, and Gateway Inc."

Samsung was charged with:

"Participating in meetings, conversations, and communications in the United States and elsewhere with competitors to discuss the prices of DRAM to be sold to certain customers; Agreeing, during those meetings, conversations, and communications, to charge prices of DRAM at certain levels to be sold to certain customers; Issuing price quotations in accordance with the agreements reached; and Exchanging information on sales of DRAM to certain customers for the purpose of monitoring and enforcing adherence to the agreed-upon prices."

For market context, the DOJ release notes: "There were approximately $7.7 billion in DRAM sales in the United States in 2004."

The Micron-internal obstruction-of-justice plea

A footnote in the cartel record that is rarely surfaced: in December 2003, Alfred P. Censullo, a Regional Sales Manager for Micron Technology, was charged with obstruction of justice (18 U.S.C. § 1503). Per the DOJ Samsung release:

"Censullo pleaded guilty to the charge and admitted to having withheld and altered documents responsive to a grand jury subpoena served on Micron in June 2002. Censullo was sentenced to serve six months of home detention."

This is a reminder that Micron, while not itself indicted, was part of the investigation's scope and produced cooperation that figured in the broader case.

Civil follow-on

In re Dynamic Random Access Memory (DRAM) Antitrust Litigation, MDL 1486, N.D. Cal. — direct-purchaser settlements totaled >$300 million. Docket available on PACER. Class plaintiffs included the named OEMs plus indirect-purchaser classes.

Why this matters for the current cycle

Three things flow from the cartel case directly to today:

  1. Behavioral coordination is closed. The producers cannot phone each other to fix prices without triggering exactly the same DOJ machinery that resulted in 18 executive jail terms. The Korean and Japanese executives involved served time in US federal prison. This is institutional memory; senior memory executives today were mid-career when colleagues were extradited.

  2. Structural coordination remains open. Each producer can independently publish its capex plan, sketch its capacity restraint, and signal its discipline. As long as no information is exchanged bilaterally, the result resembles the cartel's effect — restrained supply, supported pricing — without the per-se Sherman Act violation. The current "discipline" framing (see supply/capex-discipline.md) is the legal substitute for the cartel.

  3. The 2018 China SAMR antitrust probe was the warning shot for the new equilibrium. SAMR's May 31, 2018 investigation of Samsung, SK Hynix, and Micron came at the peak of the 2018–19 cycle. It never produced public penalties — quietly faded — but it signaled that structural coordination would be tested too if pricing got too aggressive. The producers' response since has been to keep discipline framing consistent without crossing the line into bilateral exchange.

The connection to "what's different this time"

The argument the wiki makes is: today's memory cycle looks like a managed shortage, not an organic one. The producers learned in 1995–96 that overcapacity destroys margins, learned in 2002–2007 that bilateral coordination destroys executives, learned in 2008–09 and 2012 that even disciplined producers can die, and learned in 2018–19 and 2022–23 that the cure for cyclical losses is unilateral discipline.

The Big 3 are now executing the equilibrium that 30 years of failed alternatives have selected for. The cartel case is the moment that closed the cheap alternative.
