DDR Introduction

Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a
high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs and
system integrators.
DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing
SDRAM i n frastructure, yet makes awesome advances in solving the system perf o rmance bottleneck by
doubling the memory bandwidth. DDR SDRAM w ill offer a superior solution and migration path from
existing S DRAM designs due to its availability, pricing and overall market support. PC2100 DDR
memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge of
the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM clock
frequency. With peak bandwidth of 2.1GB per second, DDR memory enables system OEMs to build
high performance and low latency DRAM subsystems that are suitable for servers, workstations, high-
end PC 's and v alue desktop SM A sy stems. With a core voltage of only 2.5 Volts compared to
conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops
and notebook applications.
