Hyperstone hyMap Flash Management

Hyperstone GmbH hyMap technology improves endurance and random write performance for flash memory systems, thus for enabling MLC for industrial embedded storage systems.

hyMap reduces Write Amplification (WAF) by a factor of more than 100 in fragmented usage pattern and for small file random writes. Thereby, the reduction in effectively used write-erase-cycles results in higher performance, longer life and shorter random access response times. As a result, in many applications hyMap together with Hyperstone controllers and MLC flash enables reliability and data retention than other controllers using SLC. hyMap does not require any external DRAM or SRAM.

Together with Hyperstone’s proprietary hyReliability feature set, hyMap provides enhanced endurance, data retention management, as well as  fail-safe features mandatory for industrial applications.

“Our hyMap FTL architecture reliably enables lower-cost MLC for embedded Flash systems, achieving better reliability and endurance than other controllers. But also SLC and pseudo SLC reliability is increased dramatically.” said Axel Mehnert, VP marketing, Hyperstone. “hyMap together with our proven hyReliability feature set is optimally suited to maximize system integrators’ flexibility, choosing the best Flash technology for specific application requirements.”

“Evaluating SSDs for enterprise applications, write amplification has been discussed intensively for several years. Controllers used in these high-performance applications use external DRAM and multi-core processors. For removable SD cards or USB modules in embedded systems, write amplification has not been in focus yet. Low-cost consumer controllers do not provide sufficient SRAM and CPU-power to provide such sophisticated mapping and FTL algorithms.” said Dr. Jan Peter Berns, MD, Hyperstone. “With hyMap we are now offering a truly efficient high-performance solution for embedded systems.“

Initially, hyMap will be available for S8 – SD/MMC and U8 – USB flash memory controllers. The new architecture will be used for all future Hyperstone products.
