LONDON – Fabless chip company Silicon Motion Technology Corp. has announced its FerriSSD chip, which it describes as the world's smallest "single-chip" solid-state drive.
The chip provides 32-Gbyte or 64-GByte of storage but it seems likely it is multiple die in a single component. It offers SATA or PATA interfaces and comes in a BGA package with both commercial-grade (0 to 70 degrees C) and industrial-grade (-40 to 85 degrees C) temperature support.
The FerriSSD is suitable for embedded storage in industrial PCs, tablets, navigation devices, point-of-sale terminals, medical devices, test instruments, and other specialty devices, Silicon Motion (Jhubei City, Taiwan) said.
The single BGA package measures 16-mm by 20-mm and offers 32-Gbytes using single-level cell (SLC) NAND flash memory and 64-Gbytes using multi-level cell (MLC) memory, SMT said. The FerriSSD includes Silicon Motion's NAND flash memory controller, error-correction code engine and wear leveling.
Silicon Motion was founded in 1995 in San Jose, California, and is traded on the Nasdaq stock exchange.
I suppose the title should have been single "package" SSD! Nonetheless, this is impressive for the application it serves, while their counterparts in DDR3/4 and wide I/O-enabled memories are still in a fraction of what FerriSSD stores (stacked/TSV-based RDRAM's by Samsung & soon by Micron? not withstanding!).
