DDR4
The fourth-generation Double Data Rate synchronous dynamic random-access memory standard. It features a mature manufacturing process and stable yield rates, and is widely used in consumer and enterprise computing platforms, representing the previous generation of mainstream memory specifications.
Timeline (last 90 days)
Against the current backdrop of memory shortages, manufacturers that had originally planned to discontinue or reduce DDR4 production are reassessing capacity allocation and restarting or maintaining DDR4 production.
Mainstream DDR4 products have been in mass production on the 1y nm (approximately 14–16 nm) and 1z nm (approximately 13 nm) nodes for many years, while DDR5 mass production is concentrated on the 1α nm (approximately 12 nm) node and even more advanced nodes.
The return of DDR4 is a stopgap measure under supply chain imbalances, not a technical regression or change in direction.
CXMT's currently publicly disclosed mass production node is at the 17 nm level, corresponding to its third-generation DDR4/LPDDR4 products.
