Aleph One

Aleph One is a British software company that develops robust low-level file systems for Flash memory, with headquarters in the United Kingdom.

Here are key aspects of the company:

• Products & Services: The company offers Yaffs, a reliable file system designed specifically for use with Flash memory and embedded applications like disk controllers.
• Industries: Their solutions operate at the operating-system level in extreme environments where radiation can cause bit damage, such as on NASA's Transiting Exoplanet Survey Satellite (TESS).
• Innovation: Yaffs features effective recovery from power-loss, wear-levelling, error correction for Flash unreliability, and guards against write amplification to ensure data integrity.

Aleph One provides flexible licensing options including GPL software availability and proprietary licences for customers who require code confidentiality while supplying versions of their file system under these terms.
