개요
Description
- Capacity: 2Gb (256M x 8)
- Speed: DDR3-1600 (800 MHz clock, 1600 Mbps/pin)
- Voltage: 1.5V (standard DDR3)
- Organization: 8 internal banks, 16-bit I/O
- Package: 78-ball FBGA (Fine-pitch Ball Grid Array)
- Applications: Consumer electronics, networking, embedded systems
It supports auto-refresh, self-refresh, and programmable CAS latency (CL=5–11). The "-BMMA" suffix denotes specific timing and industrial-grade reliability.
Use cases: Set-top boxes, routers, industrial PCs.
For detailed specs, refer to Samsung’s datasheet.

Frequently Asked Questions
Q: What is the memory capacity and package type of the K4B2G1646F-BMMA?
A: It has a 2Gbit memory size and is packaged in FBGA-96, a standard form for DDR3 SDRAM modules.
Q: What is the operating temperature range for this component?
A: The operating temperature range is -40°C to +95°C, making it suitable for industrial and extended temperature applications.
Q: What supply voltage does this memory chip require?
A: It requires a 1.35V voltage supply, which is typical for low-power DDR3L (DDR3 Low Voltage) memory, reducing power consumption.
Q: Is this component compatible with standard DDR3 interfaces?
A: Yes, as a DDR3L device, it is backward compatible with DDR3 slots and interfaces, but operates at a lower voltage for improved efficiency.
Q: What are typical applications for the K4B2G1646F-BMMA?
A: Common applications include embedded systems, industrial PCs, networking equipment, and consumer electronics requiring reliable DDR3L memory.
Q: How does the 1.35V voltage benefit system design?
A: The 1.35V supply reduces overall power dissipation and heat generation, ideal for portable or thermally constrained environments.
