Working with DRAM products
Define the required function
DRAM products is a product-line reference within CXMT / 长鑫存储. Use the manufacturer source to confirm the exact device or deliverable and its current support status.
Use the requirements below to decide which specification limits your design. A family name alone is not a purchasing specification.
Check the integration boundary
Choose the complete device and ordering code before checking package pinout, power, electrical limits and operating grade. Keep family maxima separate from a selected device or package.

What to confirm before selection
Use these checks to define the requirement. Family names alone do not establish performance, package compatibility or current availability.
- Confirm the memory technology, interface/protocol, capacity, organization and voltage against the controller.
- Review temperature grade, endurance/retention where applicable, package footprint and lifecycle notices.
Move from family to full ordering number
Identify the complete manufacturer part number, package, operating grade and electrical requirements. Reviewed FPGA specifications can then be compared at device level.

PRACTICAL QUESTIONS
DRAM products selection questions
How do I select a model within DRAM products?
Start with the documented product scope: DRAM products is a product-line reference within CXMT / 长鑫存储. Use the manufacturer source to confirm the exact device or deliverable and its current support status. Then compare the device-specific facts below with your required resources and interfaces. Open each model for its evidence and ordering constraints.
Is a base-device name enough to place an order?
A base-device identifier identifies the silicon or model, but may omit package, speed, temperature, qualification and packing options. Use the manufacturer ordering table to establish the complete code. Reference examples do not establish stock or an approved replacement.
Can the listed devices use the same PCB or development tools?
A shared family or manufacturer does not establish pin compatibility. Compare pinout, supply and I/O-bank voltages, configuration, timing, tool support and thermal limits before changing a board.
What should I include for sourcing or PCBA review?
Provide the exact part or board revision, quantity, delivery requirement, operating environment and traceability needs. For assembly, identify BOM readiness, PCB stack-up, programming access and the inspection or functional-test scope.
