概要

Description

The IS42S16320B-6TL is a dynamic random-access memory (DRAM) chip produced by ISSI (Integrated Silicon Solution, Inc.). It is a 16 Meg x 32 bits synchronous DRAM, organized as 16M x 32, which means it can store 16 million 32-bit words. The "6T" in its model number indicates the speed grade, implying it operates at a clock frequency of up to 166 MHz (6ns access time).
This DRAM is designed for high-performance applications, featuring a double data rate (DDR) interface that allows for data to be transferred on both the rising and falling edges of the clock signal. It supports a variety of power-saving features, making it suitable for mobile and portable devices. The IS42S16320B-6TL is commonly used in consumer electronics, networking equipment, and embedded systems, providing efficient data storage and retrieval capabilities. Its compact design and low power consumption characteristics make it a popular choice for applications requiring reliable memory solutions.
