founded in 1990, and based in Konstanz, Germany, is a fabless semiconductor and
microprocessor design company whose products include SSD controllers optimized
for low power applications.
|Together with subsidiaries in Taiwan,
USA and with other worldwide partners, Hyperstone serves a global customer base.
Hyperstone is a member of the CML Microsystems Plc group, traded on the London
Stock Exchange. The group currently consists of 8 subsidiaries and has over 170
Hyperstone research and development is based in Germany and
Taiwan. Industry-leading partners provide world-class wafer subcontracting,
packaging, and testing services. Hyperstone's success is based on its
proprietary 32-Bit RISC processor, optimized for flash handling applications.
Hyperstone's products include microcontrollers for
Solid State Disks (SSD),
Disk-on-Module (DoM), Disk-on-Board (DoB), embedded Flash solutions such as
eMMC, and Flash cards such as CF, SD & microSD. Flash controller firmware is
supplied complementary to the controllers and customized for each flash and
application. Hyperstone is one of the pioneers in the flash memory controller
business and owns several patents for flash handling, including wear leveling
algorithms and microprocessor design...

vast differences are the direct consequences of 2 different approaches to RAM
cache flash architecture.
- the regular design - uses a 3F capacitor - to enable enough time for the
DRAM cache to save all its data to flash
2 different architectures are explored in 0
to 3 S
- the ultra skinny design - doesn't need any hold up capacitor at all
|"For Hyperstone, the
biggest idea and industry trend that we pushed and participated in is the
implementation of page-based-FTL running on DRAM-less controller architectures.
This approach improves random write performance, increases endurance while
maintaining power-fail robustness at the same time. As this architecture also
reduces system cost it is also adopted in consumer markets.
We also see a significant adoption of USB 3.0 in industrial/embedded
markets. Certainly, the most hyped topics, at the FMS for instance, were 3D
NAND and NVMe but for both we do not yet see any sufficiently mature products or
any massive adoption in our markets"

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 higher reliability and data retention than
other controllers using SLC. hyMap does

In the same announcement - Dr. Jan Peter
Berns, Managing Director of Hyperstone - acknowledges that while these
issues have already been discussed intensively for several years in the
enterprise market. Hyperstone's new hyMap controller technology brings this
kind of improvement into smaller, low power SSDs such as SD/MMC and USB which
don't have the same kind of budgets for DRAM and CPU power as enterprise SSDs.
