SMART Modular Introduces First 4GB DDR2 CoolFlex Mini-Registered DIMMs

SMART Modular Technologies introduced the industry’s first 4GB PC2-4200 244-pin DDR2 Mini-Registered DIMM (RDIMM) designed using CoolFlex and Dual Die Package (DDP) technology.

SMART’s 4GB DDR2 Mini-RDIMM is configured as 512Mx72 with the option of utilizing either a 4-rank module using SMART-built 1Gb (256Mx4) DDPs, or a 2-rank module using 256Mx4 BGA DDR2 SDRAMs. This option provides OEMs the flexibility to transition from the 4-rank 512Mb-based option to the 2-rank 1Gb-based option as market demand drives the price crossover point between 512Mb and 1Gb devices.

This new RoHS-compliant memory module is the industry's first 4GB DDR2 Mini-RDIMM designed with CoolFlex foldable PCB technology. CoolFlex allows for doubling the memory capacity with 36 DRAM placements on four sides. The new 4GB DDR2 Mini-RDIMM is also designed with two registers and two Phase Locked Loops for reduced loading and improved signal integrity. SMART’s 4GB DDR2 Mini-RDIMM follows the JEDEC standard pin-out and has the additional Error Correction Code functionality required by many types of data-sensitive applications. Mini-DIMMs can be mounted with vertical, right-angled, or angled sockets to support design versatility.

The ordering part numbers for SMART’s newest 4GB DDR2 Mini-RDIMMs are listed in the table below:

• SG572124AG8RDDG: 4GB capacity, 1.18" height, 512MMx72 module configuration, 4 ranks, 128Mx4 device configuration
