RS70B32G4S15G Rayson eMMC5.1 32GB

Rayson eMMC product is a high quality and cost advantage embedded storage solution and compatible with JEDEC standard eMMC5.1 specification. Its strong ECC engine significantly improves error correction enabling longer device lifetime and an increased ability to handle higher raw bit error rate.

The Rayson eMMC product consists of NAND flash and an eMMC controller. The eMMC controller and software directly manage NAND flash, including ECC, wear-leveling, bad block management, garbage collection and performance optimization, and manage interface protocols. This architecture insulates any revision of NAND flash from the eMMC Host, makes the eMMC device easy to integrate and accelerates time-to-market.
