K4B4G1646Q 概要
DDR3L (Double Data Rate 3 Low Voltage) SDRAM is a type of synchronous dynamic random-access memory that operates at a reduced I/O voltage of 1.35V, compared to standard DDR3's 1.5V. This lower voltage reduces power consumption by approximately 15-20%, making it ideal for power-sensitive devices such as laptops, servers, and industrial systems. DDR3L is part of the DDR3 memory family, which uses an 8n-prefetch architecture to achieve high data rates, and is a predecessor to DDR4.
Key features of the K4B4G1646Q include a 16-bit data bus, a data rate of up to 1866 Mbps (PC3-14900), and a 96-ball FBGA package. It is lead-free and halogen-free, and RoHS compliant. The device supports a burst length of 8 (BL8) and on-die termination (ODT) for improved signal integrity. It also features programmable CAS latency and additive latency, allowing system designers to optimize performance.
Technically, the K4B4G1646Q uses Samsung's Q-die process technology, which is a 20nm-class DRAM process. This advanced process node enables higher density and lower power consumption compared to older D-die or E-die variants. The device includes an internal temperature sensor for self-refresh rate control, which helps manage power in thermally constrained environments.
Typical applications include main memory for laptops and ultrabooks, embedded systems, networking equipment, and industrial PCs. Its low voltage and high density make it suitable for designs where power efficiency and board space are critical.
When designing with this device, ensure proper decoupling capacitors are placed near the power pins, and follow the layout guidelines in the datasheet for the 96-ball FBGA package to maintain signal integrity at high data rates.

設計ノート
The K4B4G1646Q operates at 1.35V, which is lower than standard DDR3's 1.5V. Ensure the power supply can provide a stable 1.35V rail with adequate decoupling. Use multiple 0.1uF ceramic capacitors near the VDD and VDDQ pins to filter high-frequency noise, and a bulk capacitor (e.g., 10uF) for transient currents.
For the 96-ball FBGA package, follow the layout guidelines in the datasheet. Maintain controlled impedance for the data and address lines, typically 50 ohms single-ended and 100 ohms differential. Keep the trace lengths matched to minimize skew, and place the device close to the controller to reduce signal degradation.
Ensure the memory controller is configured for DDR3L (1.35V) operation, not standard DDR3 (1.5V), to avoid damage. Also, verify the speed grade matches the system requirements. Incorrect termination settings can cause signal integrity issues, so use the on-die termination (ODT) features as specified in the datasheet.
