MT41J256M8JE-15E:A

Memory IC Overview

The Micron MT41J256M8JE-15E:A is a 2Gb DDR3 SDRAM organized as 32 Meg x 8 with 8 internal banks. It operates at VDD = VDDQ = +1.5V ±0.075V and supports clock frequencies from 300 to 800 MHz. The -15E speed grade targets a data rate of 1333 MT/s with a target tRCD-tRP-CL of 9-9-9, corresponding to a cycle time of 1.5ns. It utilizes an 8n-bit prefetch architecture and differential bidirectional data strobes. The component is housed in an 82-ball FBGA package (Rev. A JE) measuring 12.5mm x 15.5mm.

Memory IC Procurement Notes

Verify the exact part number against official Micron documentation to confirm the specific speed bin, package revision, and temperature range. Ensure compatibility with system voltage requirements of 1.5V. Check for moisture sensitivity handling instructions prior to assembly. Confirm that the ordering suffix matches the required timing parameters and physical package dimensions.

Memory IC Selection Notes

Select this component based on the required 2Gb capacity and 8-bit data bus width. The -15E speed grade is suitable for systems requiring 1333 MT/s performance. Consider the 82-ball FBGA package size when designing the PCB layout. Verify that the controller supports the necessary DDR3 features such as write leveling and dynamic ODT.

Memory IC Part Context

This device belongs to the Micron MT41J family of 2Gb DDR3 SDRAMs. Other configurations in this family include 512 Meg x 4 and 128 Meg x 16 organizations. The family shares common architectural features like 8 internal banks and 8n-bit prefetch. Different speed grades and package options are available within the series to meet various performance and form factor requirements.

Memory IC Replacement Considerations

Check for other Micron parts with the same organization and speed grade but different package types, such as the 78-ball FBGA variant. Verify backward compatibility with lower speed grades if system constraints allow. Consult the official Micron catalog for alternative revisions or updated versions of the MT41J series.
