MT41K256M16RE-15E:D Overview
DDR3L (Low Voltage DDR3) is a type of synchronous dynamic random-access memory (SDRAM) that operates at 1.35V, reducing power consumption by about 15% compared to standard 1.5V DDR3. It is part of the DDR3 SDRAM family, which uses double data rate signaling to transfer data on both edges of the clock, achieving high bandwidth. DDR3L is commonly used in mobile devices, embedded systems, and servers where power efficiency is critical.
Key features include a 4Gb density, 16-bit data bus, 667 MHz clock speed (PC3L-10600), and an access time of 13.5 ns. The device supports on-die termination (ODT), programmable CAS latency, and burst lengths of 8 and 4. It operates over a temperature range of -40°C to 95°C (TC) for the industrial variant, making it suitable for harsh environments.
The MT41K256M16RE-15E:D uses a 30nm DRAM process technology, enabling high density with low power. It features a 1.35V core and I/O supply, with a separate VDDQ for improved signal integrity. The device includes auto-refresh and self-refresh modes for power saving, and supports DLL (delay-locked loop) for precise timing.
Typical applications include embedded computing, networking equipment, industrial automation, and automotive infotainment systems. Its low voltage and high density make it ideal for power-sensitive designs that require large memory capacity.
When designing with this device, ensure proper decoupling of the VDD and VDDQ pins with 0.1uF and 1uF capacitors. The DDR3L interface requires careful PCB layout to maintain signal integrity, including matched trace lengths and controlled impedance.

Key Differentiators
- Low voltage operation (1.35V) (vs MT41K256M16HA-125:E)
- Industrial temperature range (vs MT41K256M16RE-125:D)
- Wide availability (vs MT41K256M16HA-107:E)
Design Notes
For DDR3L memory, maintain controlled impedance of 40-50 ohms for data lines and 50-60 ohms for address/control lines. Keep trace lengths matched within 100 mils to ensure signal integrity. Use a solid ground plane and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDQ pin.
The MT41K256M16RE-15E:D requires a clean 1.35V supply. Use a low-dropout regulator or a switching regulator with low ripple. Ensure the power supply can handle peak current spikes during refresh and burst operations. Add bulk capacitance (10uF) near the memory device to stabilize voltage.
Although the device operates at low voltage, ensure adequate airflow or heatsinking in high-temperature environments. The industrial temperature range is -40°C to 95°C, but junction temperature should be kept below 105°C for reliability. Use thermal vias under the FBGA package to improve heat dissipation.
