概述

Description

The MT48LC4M32B2P-7:G is a dynamic random-access memory (DRAM) chip manufactured by Micron Technology. It is a 256 Meg x 4-bit (1Gbit) DDR3 SDRAM, designed for high-performance applications in computing and networking. The "MT" prefix indicates it's from Micron, while "48LC" denotes its architecture.
The "4M32" signifies that the chip consists of 4 banks with 32 bits wide data. The "B2" indicates it supports a double data rate, allowing data to be transferred on both the rising and falling edges of the clock signal, effectively doubling the data rate. The “P-7” specifies the package type and speed grade, with "7" indicating a specific timing and performance characteristic. The "G" at the end denotes that it is RoHS compliant, meaning it is free from hazardous substances.
This chip is commonly used in various applications, including consumer electronics, networking devices, and embedded systems, providing reliable performance and efficiency in memory-intensive tasks.
