Engineered for absolute thermal stability, zero-tolerance data accuracy, and broad legacy compatibility.
As Southeast Asia’s largest digital economy, Indonesia displays a unique hybrid demand for semiconductor products. While advanced sectors in Jakarta and Surabaya leverage high-performance compute arrays, a massive network of industrial machines, regional administrative offices, and public school labs (through projects funded by *Bantuan Operasional Sekolah* - BOS) rely on legacy **DDR3 SDRAM** modules.
DDR3 technology maintains a substantial footprint due to its maturity, stability, and lower deployment overheads. For manufacturing hubs in Cikarang, Karawang, and Bekasi, legacy Programmable Logic Controllers (PLCs), Human-Machine Interfaces (HMIs), and system motherboards require reliable, exact-spec DDR3 components. Replacing entire industrial platforms is capital-prohibitive; upgrading internal memory to premium-grade DDR3 is the most cost-effective path to optimizing lifecycle efficiency.
Government agencies purchasing IT infrastructure require varying levels of Local Content Requirements (TKDN). Corexis acts as an upstream partner, offering semi-knocked-down (SKD) kits and customizable PCBA layouts to help local system builders achieve compliant domestic manufacturing percentages.
Established in 2016, Corexis combines deep R&D with a massive 21,800 m² cleanroom manufacturing facility to serve global OEM/ODM needs.
Our engineering team designs custom boards utilizing high-quality DRAM silicon (Samsung, Hynix, Micron major-brand dies) to ensure broad compatibility and long-term operating durability.

| DRAM Densities | 1Gb to 4Gb per die | 2Gb to 8Gb per die | High-density single-rank configurations |
| Error Correction (ECC) | Standard Non-ECC (UDIMM/SO-DIMM) | ECC UDIMM & Registered RDIMM | Customized industrial layout options |
| Thermal Range | Commercial: 0°C to 85°C | Industrial: -40°C to 95°C | Thickened thermal pads & heat spreaders |
In many automated factories across East Java, fluctuations in power grids or high industrial ambient heat can cause memory signal attenuation. Standard consumer memory modules fail under these conditions. Corexis guarantees operational integrity by employing **8-layer, low-cross-talk PCB layouts** with **30u" gold fingers**. Our modules undergo 100% thermal chamber stress testing, assuring stability under temperature swings common in Indonesian industrial facilities.
Importing electronic components into Indonesia requires navigating local trade laws, import quotas (such as PI/Persetujuan Impor), and customs clearances through the *Indonesia National Single Window* (INSW). Corexis provides full legal export documentation, compliance-ready certificates of origin (Form E for tariff reductions), and customized packaging labels to guarantee clear customs transitions at Tanjung Priok, Soekarno-Hatta, or Tanjung Perak ports.
Our company offers flexible commercial models for domestic Indonesian electronics brands, allowing for private labeling and custom retail-ready packaging designed according to Indonesian consumer preferences.

While the focus is on maintaining stable, cost-effective DDR3 supply networks across regional Indonesia, Corexis’s R&D capabilities dynamically adapt to global semiconductor industry trajectories. Our forward-compatible motherboard layouts and design processes facilitate seamless transitions when industrial systems are ready to bridge into DDR4 and high-bandwidth DDR5 architectures.
Our engineering services enable system designers in Jakarta, Bandung, and beyond to deploy modern control systems containing custom components that interface with existing legacy network nodes, ensuring minimal capital expenditure during critical infrastructure updates.
Whether you require custom logo silk-screening, unique branding configurations, localized packaging for retail systems, specific frequency profiles, or specific memory capacity limits, Corexis’s extensive R&D facilities offer absolute flexibility.
Answers to common technical, logistics, and integration questions for purchasing managers and system integrators.
Standard DDR3 operates exclusively at 1.50V, whereas DDR3L is a low-voltage variant operating at 1.35V. DDR3L is dual-voltage capable, meaning it can function in both 1.5V legacy motherboard platforms and newer 1.35V environments. However, putting standard 1.5V-only DDR3 into a system configured for 1.35V can lead to boot failures or unstable operation due to under-voltage. We supply both formats and recommend checking CPU and motherboard specs.
Corexis works with Indonesian companies by offering Semi-Knocked-Down (SKD) kits, customized PCB assemblies (PCBA), and unbranded modules. This allows local manufacturers to conduct final assembly, packaging, testing, and integration locally in Indonesia, contributing significantly to their localized production value and TKDN compliance calculations.
Given Indonesia's tropical climate, humidity-induced corrosion and thermal stress are common failure points. Corexis uses high-durability PCBs, corrosion-resistant 30-micro-inch gold contacts, and subjects all batches to strict thermal-humidity cycling tests. Our production facilities maintain 100% full inspection, utilizing automated testing systems to ensure stable read/write cycles under elevated temperatures.
Yes. We offer comprehensive OEM/ODM services. We can flash customized Serial Presence Detect (SPD) configurations to match your legacy BIOS requirements, laser-print your brand logo on the chips/heatsinks, and provide custom retail-ready packaging styled to your exact brand specifications.
For standard memory module configurations, the MOQ begins at 100 units. For specialized industrial PCBA customizations or custom layout configurations, the MOQ is negotiated based on design complexity. Typical delivery windows from factory release to arrival in primary ports (like Jakarta or Surabaya) range from 10 to 18 business days, depending on sea/air freight preference.
