MT41J256M4JP-125:G

Memory IC Overview

The Micron MT41J256M4JP-125:G is a 1Gb DDR3 SDRAM configured as 32 Meg x 4 with eight internal banks. It operates at a nominal voltage of 1.5V and supports clock frequencies from 300 MHz to 800 MHz. The device utilizes an 8n-bit prefetch architecture with differential bidirectional data strobes and differential clock inputs. It features nominal and dynamic on-die termination for data, strobe, and mask signals. The component includes automatic self-refresh, write leveling, and output driver calibration capabilities.

Memory IC Feature Summary

• Supports selectable burst lengths of 8 or burst chop of 4 via mode register set
• Includes multipurpose register for system read calibration
• Features automatic self-refresh and self-refresh temperature modes

Memory IC Applications

• Client PC memory systems
• Data center server platforms
• Industrial IoT solutions

Memory IC Procurement Notes

Verify the specific speed grade suffix matches the required timing parameters. Confirm the package revision corresponds to the intended PCB footprint. Ensure the ordering suffix aligns with the desired configuration and environmental specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this part for designs requiring 1Gb density with a x4 interface width. The -125 speed grade targets 1600 MT/s operation. Consider the 78-ball FBGA package dimensions for board space constraints. Verify compatibility with the host controller's supported DDR3 speeds and voltage levels.

Memory IC Part Context

This component belongs to the Micron 1Gb DDR3 SDRAM family, which also includes x8 and x16 configurations. The MT41J series represents standard DDR3 technology operating at 1.5V. It is distinct from the lower-voltage DDR3L variants in the MT41K series.

Memory IC Replacement Considerations

Compatible substitutes include other Micron 1Gb DDR3 devices such as the MT41J128M8 or MT41J64M16, provided the interface width and pinout requirements are met. Cross-referencing speed grades and package revisions is essential for direct replacement.
