DDR Introduction

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 infrastructure, yet makes awesome advances in solving the system
performance bottleneck by doubling the memory bandwidth. DDR SDRAM will offer a
superior solution and migration path from existing SDRAM 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 value
desktop SMA systems. 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.
