NCP DDR2 SDRAM

Introduction

NCP DDR2 (Double Data Rate 2) SDRAM is a high-density memory that achieves high-speed operation and low power consumption at the same time. This is also the key requirement of high-end systems across the board. NCP DDR2 will be the ultimate choice for enhancing your experience with PC Games and Home Entertainment.

NCP DDR2 SDRAM achieves a data transfer rate of up to 533Mbps, double the data transfer rate of DDR266, and its 1.8V operation provides lower power consumption than DDR SDRAM. Additionally, DDR2 SDRAM is available in an FBGA (Fine-pitch Ball Grid Array) package that saves space in the system and enables fine signal integrity.
