Macrotron is producing 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 128MB, 256MB, 512MB, and 1GB with both 64 bit and 72 bit (ECC)
words operating at 400MHz. In order to meet these clock
frequencies Macrotron uses 400MHz memory devices from major
brand suppliers. This clock speed results in a 3.2 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. Including workstation
and server markets as well as the high volume, cost sensitive, PC market.
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.
