The Memory CCG focuses on the developing of high performance, high availability and high endurance SSD Controllers for next generation mass storage and secured data storage applications.
A flexible Flash storage device design platform was built in to facilitate the development of SSD Controllers with various host interfaces, different capacities, error correction coding (ECC) and encryption capabilities.
The following describes the storage design platform, technology and featured highlights and application examples of our high performance SSD controllers:
High Performance SSD Controller
Data Packaging Efficiency (UASP)
Key goals of UASP
- Supports multi-commands queue and return full SCSI status and sense data
- Leveraging USB3.0 streaming capability to implement the multiple commands queuing
- Asynchronous notification thanks to USB3.0 dual-simplex transaction
- Improves 30% efficiency comparing to current Bulk Only Transaction (BOT) protocol for Mass Storage Class
Application Examples of High-performance, High-availability SSD
NVMe (Non-Volatile Memory Express ) Controller for Enterprise SSD
- Native PCIe interface NAND Flash Storage
- Provides high efficient solid state storage platform for enterprise application
- Enterprise Data Center and Cloud Storage
