MT41K256M16RE-125:D 概要
DDR3L SDRAM (Double Data Rate 3 Low Voltage) is a type of synchronous dynamic random-access memory that operates at 1.35V, reducing power consumption by about 20% compared to standard 1.5V DDR3. It is part of the DDR3 family, which uses double data rate signaling to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is backward compatible with DDR3 and is widely used in servers, laptops, and embedded systems.
Key features include a 4Gb density, 256Mx16 organization, 1.35V supply voltage, and a CAS latency of 11 (CL11) at 1600 MT/s. The device supports on-die termination (ODT), programmable CAS latency, and burst lengths of 8 and 4. It also features auto-refresh and self-refresh modes for power saving. The FBGA-96 package offers excellent thermal and electrical performance, making it suitable for space-constrained designs.
Technically, the MT41K256M16RE-125:D uses Micron's advanced DRAM process technology, providing high reliability and low leakage. The device includes a temperature-compensated self-refresh (TCSR) feature that adjusts refresh rate based on temperature, enhancing data integrity. The 1.35V operation reduces I/O power, and the 96-ball FBGA package with a 0.8mm ball pitch ensures good signal integrity.
Typical applications include DDR3L memory modules for servers, networking equipment, industrial PCs, and embedded systems. It is also used in consumer electronics like set-top boxes and routers. The low voltage and high density make it ideal for power-sensitive designs.
When designing with this component, ensure proper decoupling capacitors near the power pins and follow the layout guidelines in the datasheet to minimize signal integrity issues. The device requires a stable 1.35V supply and a reference voltage (VREF) for the I/O.

主な差別化要因
- Lower voltage operation (1.35V) compared to standard DDR3 （vs MT41K256M16TG-125)
- Higher data rate (1600 MT/s) than the -15E variant （vs MT41K256M16RE-15E:D)
- Same package and pinout as other Micron 4Gb DDR3L parts （vs MT41K256M16HA-125:E)
設計ノート
Ensure a stable 1.35V supply with low ripple. Use a dedicated voltage regulator for VDD and VDDQ, and place 0.1uF and 1uF decoupling capacitors close to each power pin. The VREF should be generated from a precision divider and bypassed with 0.1uF capacitor.
Follow the layout guidelines in the Micron datasheet for DDR3L routing. Maintain controlled impedance for DQ, DQS, and address/command lines. Keep trace lengths matched within 50 mils for each byte lane. Use ground planes to minimize noise and ensure proper signal integrity.
The FBGA-96 package has a thermal resistance of approximately 20C/W. For high-temperature environments, ensure adequate airflow or a heatsink. The maximum operating temperature is 95C, so calculate the power dissipation and verify the junction temperature stays within limits.
