JSR364G168NHR-L-SU

Memory IC Overview

The JSR364G168NHR-L-SU is a 4Gb DDR3L SDRAM manufactured by Jeju Semiconductor Corp. It features a 256 Meg x 16 organization and operates at a nominal voltage of 1.35V, with backward compatibility to 1.5V. The device utilizes a 96-ball FBGA package (7.5mm x 13.0mm) and supports an industrial temperature range from -40°C to +95°C. Key timing parameters include cycle times of 0.938ns for DDR3-2133, 1.071ns for DDR3-1866, and 1.250ns for DDR3-1600.

Memory IC Feature Summary

• Supports differential bidirectional data strobes and differential clock inputs for high-speed signal integrity.
• Features an 8n-bit prefetch architecture with eight internal banks for concurrent operation.
• Includes programmable CAS latency, additive latency, and write latency via mode registers.
• Provides dynamic on-die termination for data, strobe, and mask signals.

Memory IC Applications

• High-bandwidth memory systems requiring low power consumption
• Industrial computing environments operating in extreme temperatures
• Embedded systems utilizing DDR3L backward compatibility

Memory IC Procurement Notes

Verify the specific speed grade suffix against the required system clock frequency. Confirm that the 96-ball FBGA footprint matches the target PCB layout dimensions. Ensure the design accommodates the specified thermal derating requirements for ODT resistance and impedance at maximum operating temperatures.

Memory IC Selection Notes

Select this component when a 4Gb density with a 16-bit interface is required. Choose the L-suffix variant for designs targeting 1.35V operation or those needing flexibility to operate at 1.5V. Verify that the host controller supports the necessary burst lengths and on-the-fly switching capabilities defined in the mode registers.

Memory IC Part Context

This part belongs to the JSR364Gxx8xxx-SU family of 4Gb DDR3(L) SDRAMs. It shares architectural similarities with other members of the series but differs in organization and package type. The x16 configuration distinguishes it from the x8 variants, which utilize a smaller 78-ball package.

Memory IC Replacement Considerations

The datasheet lists the JSR364G168NHR-A-SU as a similar level replacement with the same pinout and package. Verify electrical specifications and timing parameters before substitution.
