Application of Ferroelectric Memory GX85RS128 Compatible with MB85RS128/FM25V01 in Communication Base Station Equipment

In 5G communication networks, communication base stations are the infrastructure of mobile communication networks, responsible for wireless signal transmission between wired communication networks and wireless terminals. They require 24-hour uninterrupted operation and undertake tasks such as signal transmission and reception, data forwarding, and user access management. Base station equipment also requires long-term stable storage of two key data types: configuration data and operation logs. Traditional storage solutions (such as EEPROM and Flash) have problems with short erase life, slow write speed, and poor low-temperature performance. This article recommends using the 128K ferroelectric memory GX85RS128, which completely solves the problems of short erase life, slow write speed, and poor low-temperature performance.

The ferroelectric memory GX85RS128 is a non-volatile memory based on ferroelectric materials, using SPI communication interface, supporting 40MHz high-speed read commands, and operating voltage range of 2.7V~3.6V. Its performance can replace MB85RS128 and FM25V01 with PIN TO PIN as a new storage solution. The main functions of GX85RS128 and MB85RS128/FM25V01 are introduced as follows:

From the comparison of the three memory functions above, it can be seen that their core features are highly compatible with the storage requirements of communication base stations for "safety, efficiency, reliability, and durability". The non-volatile and nearly infinite erase and write life of the ferroelectric memory GX85RS128 can ensure the long-term security of critical data for communication devices. Its high-speed read and write performance captures transient event data from base stations, fundamentally solving the risk of loss of critical data from base stations.
