Price fixing controversy

In 2004–2005 an investigation was carried out into a worldwide DRAM price fixing conspiracy during 1999–2002 that damaged competition and raised PC prices. As a result, Samsung is to pay $300 million fine, Hynix was to pay $185 million in 2005, Infineon: $160 million in 2004. Micron firmware copy Technology cooperated with prosecutors and no fine is expected.

AENEON

AENEON was introduced in 2005. AENEON is a DRAM memory family of Infineon and fits into standard PCs and notebooks.
AENEON targets whitebox (non-brand) PC and notebook manufacturers world wide, as well as the European retail segment and end users (web shop). AENEON DRAM memory focuses the "price-performance maker club" segment.

Price advantages are obtained due to a limited product portfolio (only unbuffered and SO-DIMM), and due to outsourced module assembly. The DRAM components, however, are "Made by Infineon ".

• MCU Lockbit Lock Configuration Best Practices

  Tiered MCU Lockbit Lock Configuration Best Practices for Commercial Embedded Products. Strategic, tiered configuration of the mcu lockbit lock OTP memory array stands as the most cost-effective first line of defense to prevent unauthorized read-out of an EEPROM processor access, malicious memory dumping, and proprietary firmware tampering in mass-market commercial embedded products. Many product developers misuse lockbit functionality by implementing simplistic all-or-nothing locking schemes that create unnecessary deployment limitations while failing to optimize security granularity. Industry-leading best practices mandate partitioning the available lockbit OTP bits into five distinct functional domains to create graduated security boundaries aligned with product lifecycle requirements. The first domain consists of debug lockbits that permanently disable JTAG, SWD, and proprietary programming interfaces after end-of-line production programming. These bits prevent external tools from initiating any direct memory read or write commands that would enable immediateread-out of an EEPROM processor and flash memory data extraction. The second domain encompasses user memory lockbits that block external modification and dumping of primary application flash and general-purpose EEPROM partitions. These bits secure the core product firmware and user configuration data without restricting critical factory test functionality required during manufacturing. The third domain comprises bootloader lockbits that prevent modification or reprogramming of the immutable primary boot code responsible for secure boot initialization. Protecting the bootloader eliminates the most common vector for software lockbit bypass exploits used to dump flash and eeprom memory via manipulated boot sequences. The fourth domain includes peripheral access lockbits that disable unused high-risk buses such as unpopulated UART, CAN, and SPI interfaces to eliminate covert memory leakage pathways. Restricting idle peripherals reduces the attack surface available for bus sniffing and side-channel data inference attempts. The fifth and highest-priority domain features crypto domain lockbits that isolate hardware key storage regions from all user and debug access pathways under all operational conditions. These dedicated bits prevent even partially compromised devices from allowing threat actors to attempt to copy contents of crypto memory containing root authentication and encryption secrets. Implementing this five-tier lockbit partitioning fundamentally raises the complexity and cost of malicious microcontroller reverse engineering targeting commercial embedded hardware. Adversaries can no longer compromise a single lockbit boundary to gain full device access and must bypass multiple independent security domains sequentially. Each tier requires unique exploit techniques ranging from software bootloader manipulation to invasive die probing, significantly increasing the technical skill and equipment requirements for successful device compromise. Tiered lockbit layouts also increase the difficulty of successful decapsulation and code recovery operations by scattering individual security control gates across physically separated regions of the silicon die. Attackers cannot target a single die location to disable all lockbit functions and must perform multiple precise probing operations across distant circuitry nodes. This spatial dispersion increases the risk of die damage and data corruption during physical analysis workflows. Beyond partitioning, additional lockbit configuration best practices govern OTP programming timing and access control during production. Developers should program all non-debug lockbits during early wafer testing rather than post-assembly to eliminate intermediate access windows during component packaging and board assembly. Lockbit state should be locked from modification immediately after programming to prevent factory insider tampering with security configurations. Unique device-specific lockbit masking should be applied across product batches to prevent generic exploit tools from working across multiple device units. Lockbit integrity hash values should be stored in secure OTP regions to detect runtime tampering with lockbit state registers during field operation. Implementing these production-focused practices eliminates supply-chain vulnerabilities that enable covert pre-deployment firmware leakage and device cloning. Collectively, these tiered configuration and production guidelines transform basic mcu lockbit lock hardware into a comprehensive security framework that fundamentally blocks unauthorized end-to-end firmware extraction for commercial embedded products. When combined with firmware encryption, secure boot validation, and runtime tamper response logic, properly configured lockbit domains create a defense-in-depth strategy that balances manufacturability, field serviceability, and robust anti-reverse engineering protection for mass-market embedded hardware.
