The price of DDR4 memory has recently experienced another significant spike, with reported increases of up to 10,000% in some cases. According to statistics from the global technology industry supply chain analysis platform DigiTimes, from late September to November, spot prices for memory modules rose substantially. The price for a DDR4 16GB (8GBx2) kit increased by over 90% in a single month, while the price for a DDR5 16GB kit surged by 102% – far exceeding the price increase of gold during the same period.

The fundamental reason behind the rising memory prices is a severe imbalance between supply and demand. The current market is characterized by continuously constrained supply alongside robustly growing demand. Particularly, strong, inelastic demand from the following three key application areas is persistently consuming the increasingly tight DDR4 inventory.

1. Industrial Computers & IPCs: A Stable Foundation of Long-Term Demand

Industrial computers and Industrial PC (IPC) equipment form a solid foundation for DDR4 demand. Due to the specific requirements of the industrial sector for system stability, compatibility, and long product lifecycles, a shift to newer memory specifications for these devices is unlikely within the next two to three years, or even longer. From production line control in smart factories to embedded systems in medical devices, and from traffic control to energy management, the demand for DDR4 in these critical applications continues to grow.

2. AI Server Architecture: An Unexpected Source of Demand Growth

In the realm of AI servers, DDR4 has found a new and significant purpose. While GPUs and core computing units have widely adopted HBM and DDR5, DDR4 remains the mainstream choice for components within the server such as switches, network interface cards, and management modules. These components play a critical role in data exchange and system management within AI server clusters, and their demand increases in tandem with the expanding scale of AI server deployments.

3. Cloud Service Providers: Sustained Inventory Consumption

Within the data centers of major global Cloud Service Providers (CSPs), a vast number of servers based on DDR4 architecture remain in operation. These servers are not only numerous but also have relatively long refresh cycles. Driven by the goal of maximizing return on investment, CSPs often prefer to scale up and upgrade existing equipment to meet growing business needs. This strategy ensures a steady and stable demand for DDR4 in the data center sector.
