MT44K32M18RB-125E:A

Memory IC Overview

The Micron MT44K32M18RB-125E:A is a 576Mb RLDRAM 3 component with a 32 Meg x 18 organization and 16 banks. It operates at a clock frequency of 800 MHz (tCK = 1.25ns) with a minimum cycle time (tRC) of 8ns, supporting a peak bandwidth of 76.8 Gb/s. The device utilizes a 168-ball Pb-free FBGA package and features 1.2V center-terminated push/pull I/O. It supports extended operating ranges from 200 to 1066 MHz and includes integrated on-die termination.

Memory IC Feature Summary

• Includes an on-die DLL to generate edge-aligned data and differential output clock signals.
• Features programmable read/write latency and burst length configurations via mode registers.
• Provides integrated on-die termination and output driver calibration capabilities.

Memory IC Applications

• High-performance networking equipment
• Telecommunications infrastructure systems
• Enterprise storage controllers

Memory IC Procurement Notes

Verify the specific speed bin and temperature grade against the official Micron catalog before procurement. Confirm that the -125E suffix aligns with the required 800 MHz clock frequency and 8ns tRC timing specifications. Ensure the 168-ball FBGA package matches the target PCB footprint design constraints.

Memory IC Selection Notes

Select this part when a 576Mb capacity with a 18-bit data width is required for memory-intensive applications. Consider the 16-bank architecture for improved concurrency compared to lower-density alternatives. Verify compatibility with system voltage requirements, specifically the 1.35V VDD and 1.2V VDDQ levels.

Memory IC Part Context

This component belongs to the Micron MT44K series of RLDRAM 3 devices. It shares architectural similarities with the MT44K16M36 variant but differs in organization and data bus width. Both variants utilize the same 168-ball FBGA package form factor within the broader RLDRAM 3 family.

Memory IC Replacement Considerations

Consult the official Micron product catalog for verified substitutes. Cross-reference speed bins and package types to ensure functional equivalence without redesigning the host board layout or electrical interface.
