Ramtron International Corp.'s FM22L16 4Mb ferroelectric random access memory (F-RAM) has been selected by Shenzhen-based SBS Science & Technology Co. Ltd (SBS) for its innovative solid-state disk (SSD) data storage devices.
Apart from retaining data when power is removed, F-RAM memory offers virtually unlimited reads and writes with no write delay and very low power consumption. This unique feature set, combined with 4Mb of data storage capacity, makes Ramtron’s FM22L16 a compelling solution for SBS in its industrial SSD products.
SBS will deploy the FM22L16 along with a standard Hard Disk Drive (HDD) interface and controller to store the virtual block-to-sector map for the Flash memory in the SSD. Flash memory is prone to wearing out prematurely due to its limited write endurance. The block-to-sector map is used to store the frequently updated address locations for the data in the SSD, which reduces wear on the Flash memory. Since virtual block-to-sector maps are written frequently and need to be stored when power is removed, F-RAM is an ideal choice due to its extremely high read/write endurance and low power consumption. F-RAM-enabled SSDs are well suited for industrial applications since they have no moving parts or mechanical failure points that are common in rotating hard disk drives.
SBS specializes in the R&D and manufacturing of international standards-based embedded hardware and software that targets industrial automation markets, such as railway transportation, electric power, medical equipment, and motion control applications.
