Product overview
The UT8SD4MQ2G72 combines nine DDR4 die in an 18 GB memory module organized as 16 GB of data storage plus 2 GB for ECC. Its 72-bit interface supports data rates up to 2400 MT/s for high-performance computing, AI and machine-learning processing, RF signal processing and SSD buffering. Dedicated reset signals allow the system controller to recover an affected die while other die remain in self-refresh. Command/address parity and low-power self-refresh support system-level integrity and power management. The module uses a 266-ball package, with radiation-assured ordering options and screening flows selected for the application.

More about this product
Product features
- 18 GB module organized as 16 GB data plus 2 GB ECC
- Dedicated RESET for each die
- Command/address parity
- Maximum Power Savings Mode and low-power auto self-refresh
Die-level recovery
Individual reset inputs support recovery of a die affected by a single-event functional interrupt. System-level ECC and recovery logic remain part of the memory-controller implementation.
Select the screening flow
Ordering options include PEM QD, Space PEM QD and Space PEM Level 2. Choose the radiation-assurance and screening combination required by the mission.
Applications
