GXSC FRAM Replaces MB85RS128/FM25V01 in Solid-State Laser Applications

Solid-state lasers are widely used in high-end fields such as precision laser processing, laser ranging, and precision detection. Their control systems require high-frequency logging of laser operating parameters and real-time preservation of operational status. During the operation of solid-state laser equipment, scenarios such as high-frequency parameter refreshing, instantaneous power outages, and long-term continuous standby are common. Traditional EEPROM and Flash memory devices suffer from shortcomings including slow write speeds, limited write/erase endurance, and susceptibility to corruption during power-off writes, making them unable to meet the storage demands for precise control and long-term reliable operation of lasers.

GXSC FRAM, built on advanced ferroelectric memory technology, offers zero-latency real-time writing and ultra-high read/write endurance of up to one million cycles. Compared with traditional memory devices, it completely eliminates write-waiting latency and write/erase endurance bottlenecks, enabling high-frequency, zero-loss data storage. It is ideally suited for scenarios such as high-frequency parameter logging, power-fail parameter preservation, and fault log storage in solid-state lasers.

GXSC FRAM operates at frequencies up to 25MHz and supports a 40MHz high-speed read command. It features excellent data retention capability, guaranteeing reliable data retention for 10 years at 85°C (200 years at 25°C) across the industrial temperature range, with no need for an external battery backup. This significantly simplifies system hardware design and reduces design costs.
