Best in class NAND Endurance Technologies (eBoost)
- Write enhancement
SKHMS America is pioneering advanced NAND write techniques, adapting the write process over time to match the changing cell characteristics. These write optimizations enable both endurance and performance (lower tProg) gains.
- Advanced Error Correction (ECC)
SKHMS America has a long history in ECC leadership, having introduced LDPC coding to the mobile HDD market. Our NAND controllers have historically provided stronger error correction than NAND requirements (LM87800 supports t=120/2KB BCH code) providing endurance and reliability improvements. SKHMS America is continuing to provide ECC leadership by introduce LDPC controllers in the near future.
- Adaptive DSP
SKHMS America’s NAND controllers incorporate advanced digital signal processing (DSP) functions to adaptively track NAND media changes. These DSP functions enable optimal detection in the presence of time varying charge loss as well as intercell interference. Both hard and soft (probability) decision ECC decoders are supported.
- NAND Management
This set of firmware technologies encompass functions such as wear-levelling, garbage collection and defect management. Functions such as background media scan ensure that we have sufficient margin to recover data in the event of extended un-powered storage of the drive.
- Best in class NAND Performance Technologies
SKHMS America’s NAND controllers are optimized for sustained, high IOPs with ultra low latencies, even under heavy mixed workloads.
- High Performance Hybrid HDD Controller solutions
Leveraging SKHMS America’s extensive IP portfolio for Hard Disk Drives (HDD) and combining that technology with SKHMS America’s market leading eBoostTM digital signal processing and unique advanced error recovery technologies for Solid State Drive (SSD) controllers, SKHMS America has developed a new ultra efficient approach to linking the high-capacity, low-cost features of a HDD with the high-performance, low-power consumption features of an SSD. SKHMS America has developed a proprietary high speed interface between the hybrid NAND controller and traditional HDD controller, which can deliver the fast-boot / instant-on user experience of a SSD while simultaneously giving the user full access to the much larger storage capacity of a HDD that is expected in today’s PC applications.
