Memory controller IP aids SoC Flash integration
Denali Software and Samsung Electronics are working to develop and deliver IP products that enable fast, efficient deployment of OneNAND interfaces for SoC designs.
Software takes on SoC register management
New software boosts SoC design efficiency by automating the generation and management of the vast numbers of on-chip control registers in complex chip designs.
The advanced solution addresses key issues associated with single-level cell (SLC) and multilevel cell (MLC) NAND and provides significant advantages for system boot applications.
Flash has become a primary storage medium for various consumer electronic devices, including personal media players, high-end cellphones, navigation devices and solid state drives.
Today's system developers require a comprehensive hardware and software solution that addresses all of the performance and reliability requirements for future flash devices using smaller geometries and bit cells.
"System manufacturers face a huge challenge to integrate various NAND chips into their systems", states Nam Hyung Kim, Director and Principal Analyst at iSuppli Corporation.
"Therefore, flexible solutions and technologies, developed to speed up OEMs' time to market and to save BOM costs effectively, represent a large market opportunity".
The new technology is an innovative layer built on top of a Bose, Ray-Chaudhuri, Hocquenghem (BCH) algorithm.
As Flash has been used for the last few years, controller manufacturers have realised that the cost-related benefits of moving to multibit cells have come with inherent quality issues.
To address these issues, Denali has teamed with several leading Flash manufacturers to provide this superior technology.
"With this new technology, Denali is addressing not only the silicon resource cost and performance needs of hardware designers developing mobile and consumer electronics", says Robert Pierce, Senior Director of Flash Products at Denali Software.
"This solution is well suited for applications that need high-density memory, direct NAND boot with enhanced performance, superior quality and high reliability".
"We are providing a newly optimised Databahn NAND system solution which enables direct boot from SLC/MLC without having to complicate the boot process".
