DRAM Module for System on LSI
Kazumasa Yanagisawa, Jun Sato · 1998
INTRODUCTION GENERALLY the purpose of an information processing system is transmitting, processing, and storing the information. Among these purposes, a memory supports information processing and handles accumulation. Problems were a few when the volume of information was small. However, information volume subsequently increasing, the transmission efficiency between memory and logic began to limit overall performance. As a countermeasure, extensive work was expended in creation of cache ststens for information volume. When building a total system using semiconductors, provision of optimum transmission capabilities is required. Optimal combination of unit memory, represented by the DRAM, logic LSI with embedded memory, and system control LSI is therefore very important.
