Arasan's NAND FFS Simplifies Embedded Software Code and Data
                            Management

SAN JOSE, Calif., March 8, 2010 (GLOBE NEWSWIRE) -- Arasan Chip
Systems, Inc. ("Arasan"), a leading provider of Total IP Solutions,
announced the release of its NAND Flash File System (FFS) software.
This portable NAND FFS complements Arasan's proven ONFI 2.2 NAND Memory
Controller IP cores.

The growing sophistication of devices such as media players, gaming
consoles, smartphones and netbooks has resulted in a dramatic increase
in software and non-volatile data storage requirements. Storage of boot
code, proprietary data, security keys, media files and user generated
content requires a robust FFS to manage this content.

Arasan's NAND Flash File system abstracts the management of NAND
memory, to ease its use by application level software. It automates
handling of garbage collection, bad block management and wear-leveling
management. The FFS is architected to be easily ported to multiple OS
and platforms and supports multiple file systems. It can interface to
both SLC and MLC types of NAND memory, allowing the system designers to
trade-off between reliability and storage capacity. By integrating
wear-leveling, the FFS extends the life of the NAND memory array.
Architected to have a low host processor overhead, this FFS can easily
be used in embedded devices for improved boot speed, higher security
and reliability.

Commenting on the growing content and complexity of non-volatile memory
in embedded systems and consumer electronics, Somnath Viswanath,
Product Marketing Manager at Arasan, said, "While the introduction of
managed NAND memory solutions simplified the development of NAND memory
controllers in SoCs, there is still a significant amount of processing
that needs to be done in software. Arasan's NAND FFS handles this
complexity to simplify application development while ensuring efficient
utilization of the underlying NAND memory array."

Arasan complements this software with its portfolio of NAND Memory
Controller IP cores which support the latest ONFI 2.2 specification.
The IP cores support the highest transfer modes of up to 166MBps (in
Sync mode 4) and 200MBps (in Sync mode 5) while incorporating all of
the new features of ONFI 2.2 such as enhanced power management, ECC
information, interleaved reads, small data movement and other commands
that improve performance. The IP core can also stop the clock during
writes to save power.

Arasan provides a Total IP Solution for its NAND Memory IP consisting
of RTL source code for NAND Memory controllers, verification IP, Flash
File system software, hardware development kits and documentation all
backed by our World-class customer support.
