Product details

VL-MM9-4EBN - 4GB DDR3L SODIMM (PC3-12800), 204-Pin, Non-ECC Unbuffered Memory Module

VL-MM9-4EBN is a VersaLogic DDR3L SODIMM memory module designed for embedded and industrial systems that require stable performance, wide operating temperature options, and JEDEC-compliant DDR3/DDR3L operation. It is a 4GB (512Mx64), non-ECC, unbuffered 204-pin SODIMM rated for PC3-12800 (DDR3-1600 class).

Product Introduction

The VL-MM9-4EBN is a compact DDR3 SDRAM SODIMM memory module intended for installation into a standard 204-pin SODIMM socket. It implements a 64-bit data bus (x64) and is commonly deployed in embedded computers, industrial controllers, and rugged systems where memory stability and compatibility are critical.

This module is characterized as low voltage DDR3L capable, supporting the common DDR3/DDR3L supply ranges (1.35V nominal for DDR3L, and 1.5V nominal for DDR3 operation depending on platform requirements). For production use, it's recommended to verify your motherboard/CPU memory controller compatibility (DDR3 vs DDR3L, rank support, and speed grade).

From a construction perspective, this class of module typically integrates multiple DDR3 SDRAM devices on the PCB, and includes SPD EEPROM (Serial Presence Detect) for automatic memory parameter configuration during boot.

Key Benefits

Embedded-Friendly DDR3L Form Factor

Standard 204-pin SODIMM footprint for wide compatibility with embedded SBCs and industrial PCs.

PC3-12800 Performance Class

Supports DDR3-1600 class throughput for responsive HMI, edge computing, and data buffering tasks.

Non-ECC Unbuffered Simplicity

Ideal for platforms that require standard non-ECC memory (common in compact embedded systems).

SPD EEPROM for Plug-and-Play

SPD enables the system firmware to read timing configuration automatically, reducing integration effort.

Technical Features

Module Type

4GB 512Mx64 DDR3 SDRAM, non-ECC, unbuffered SODIMM.

Speed Grade

PC3-12800 (DDR3-1600 class fast data transfer rate).

JEDEC-Compliant Operation

Supports typical DDR3/DDR3L supply and timing ranges used by embedded memory controllers.

Prefetch Architecture

DDR3 8-bit prefetch architecture enabling efficient burst transfers.

On-Die Termination Support

Includes nominal and dynamic ODT capability typical of DDR3/DDR3L designs.

SPD + Thermal Sensing

SPD EEPROM is commonly integrated; some builds include an onboard thermal sensor for monitoring.

Pin / Interface Summary (SODIMM)

As a standard 204-pin DDR3 SODIMM, VL-MM9-4EBN follows common DDR3 signal group definitions: address inputs (A), bank address (BA), data (DQ), data strobes (DQS/DQS#), clocks (CK/CK#), chip select (CS#), row/column strobes (RAS#/CAS#), write enable (WE#), reset (RESET#), on-die termination control (ODT), reference voltages (VREF), termination voltage (VTT), and SPD I²C pins (SCL/SDA).

If you need, I can generate a clean "Pin Description" table版式(不逐条抄204pin,而是按信号组汇总),更适合放在产品页里.

Equivalent & Manufacturer Information

Equivalent / Alternative Options

For embedded SODIMM memory, "equivalents" are generally defined by matching: capacity (4GB), DDR3L/DDR3 voltage, PC3-12800 speed, 204-pin SODIMM, and system constraints (rank, height, temperature screening).

4GB DDR3L 204-pin SODIMM, PC3-12800, non-ECC unbuffered (same class)
Industrial-temperature 4GB DDR3L SODIMM variants (for -40°C to +85/+95°C systems)

To avoid boot issues, always confirm the module's SPD timing table, rank density, and platform whitelist (some embedded BIOS lock to validated vendor modules).
