Macrotron Announces the Availability of DDR SDRAM Modules

Macrotron has released to production DDR (Double Data Rate) SDRAM (Synchronous Dynamic Random Access Memory) Modules in the standard 184-pin DIMM (Dual Inline Memory Module). These modules include the 64MB, 128MB, 256MB, 512MB, and 1GB with both 64 bit and 72 bit (ECC) words operating at 266MHz. In order to meet these clock frequencies Macrotron uses 266MHz memory devices from major brand suppliers. This clock speed results in a 2.1 GB/second module data transfer rate.

DDR SDRAM is an evolutionary new technology derived from the widely used SDRAM technology. The future success of DDR is the high performance gained by being able to perform two data operations in one clock cycle. DDR has twice the throughput of standard SDRAM; hence Double the Data. The evolution of DDR on top of standard SDRAM offers cost benefits since manufacturers will use existing wafer fabs, processes and tester technology. The other benefit is that time to market with production devices has been expedient.

Macrotron has embraced the DDR SDRAM modules as the most logical and cost effective approach to providing the next generation memory for its customers. The DDR increases memory bandwidth by clocking data on both the rising and falling edges of the memory clock, while maintaining the low latency of standard SDRAM (Single Data Rate). The DDR module implementation used simulation and verification to ensure proper timing requirements and signal integrity in the design. This follows the JEDEC defined 184-pin unbuffered DDR SDRAM DIMM product per JEDEC standard JESD21-C, section 4.5.10.

The DDR modules are well suited for a broad range of applications. Initially the workstation and server markets will be served where the high speed can enhance the performance of these markets. Major trade news sources have reported that the DDR format will eventually be used in the high volume, cost sensitive, PC market over the competing Rambus architecture. The primary reason is that there is a reported large price premium for the Rambus module with little or no performance improvement over the DDR module.

DDR provides a cost-effective, high-performance main memory solution that requires minimal development and manufacturing investment while at the same time maintaining a cost structure consistent with standard SDRAMs.

Macrotron's DDR SDRAM modules are manufactured with the same dedication to quality and high standards utilizing our new state-of-the-art facility located in Silicon Valley. Macrotron has joined with several major device manufacturers to insure availability of product in a timely manner at a competitive price.
