MT40A1G8SA-075:E 概要
DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is a type of volatile memory that transfers data on both rising and falling edges of the clock signal, effectively doubling the data rate. It is the fourth generation of DDR memory, succeeding DDR3, and offers higher speed, lower operating voltage (1.2V), and improved power efficiency. DDR4 is a critical component in modern computing systems, servers, and embedded devices, forming the main memory hierarchy alongside storage and cache.
Key features of the MT40A1G8SA-075:E include a supply voltage of VDD = VDDQ = 1.2V ±60mV, with VPP at 2.5V (-125mV, +250mV). It supports on-die, internal, adjustable VREFDQ generation and 1.2V pseudo open-drain I/O. The device offers a refresh time of 8192 cycles with temperature-dependent refresh rates: 64ms at -40°C to 85°C, 32ms at >85°C to 95°C, and 16ms at >95°C to 105°C. Additional features include write leveling, dynamic on-chip termination, CRC function, and data mask function, ensuring signal integrity and reliable operation.
Technically, the MT40A1G8SA-075:E utilizes Micron's advanced DRAM process technology, achieving high density and performance while maintaining low power. The 78-ball FBGA package with a 7.5x11 mm footprint is optimized for space-constrained PCB designs, offering excellent thermal and electrical characteristics. The device supports a data rate of 2666 MT/s, providing a peak bandwidth of 21.3 GB/s per module (when paired with a 64-bit bus).
Typical applications include high-performance computing, servers, networking equipment (routers, switches), and industrial automation systems. Its high speed and reliability make it suitable for memory-intensive tasks such as data analytics, virtualization, and real-time processing. The low operating voltage contributes to energy-efficient designs, crucial for data centers and battery-powered devices.
When designing with this component, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the Micron datasheet to minimize signal integrity issues. The device requires a stable 1.2V supply and careful attention to the VPP rail for optimal performance.

設計ノート
For high-speed DDR4 routing, maintain controlled impedance of 40-50 ohms for data lines and 80-100 ohms for address/control lines. Keep trace lengths matched within ±10 mils for DQ/DQS groups. Use ground planes beneath the FBGA package to minimize inductance and crosstalk.
Decouple VDD and VDDQ with 0.1uF and 1uF ceramic capacitors placed as close as possible to the power balls. Use a 10uF bulk capacitor per power rail. Ensure VPP is clean and stable, as it is used for word line boosting. Follow Micron's power supply sequencing requirements.
The MT40A1G8SA-075:E dissipates up to 1.5W under heavy load. Ensure adequate airflow or a thermal pad to the PCB to keep the junction temperature below 95°C. The FBGA package has a thermal resistance of approximately 20°C/W; verify with thermal simulation.
