Shark Eliminates Need To Use NOR Flash For Booting Purposes

SUNNYVALE, CA, May 20, 2003 - SanDisk Corporation (NASDAQ:SNDK) today introduced its Shark tool kit to support design-in of MLC (multi-level cell) NAND and binary NAND flash memory components. The Shark tool kit is a high performance HDL model that enables a designer to quickly build a NAND flash interface into ASIC or system-on-chip (SOC) designs.

Shark decreases development time and production costs and minimizes system overhead for NAND flash memory devices in consumer and industrial products, including mobile phones, handheld computers, digital cameras, camcorders, MP3 players, industrial computers and automotive and telecommunications systems. With its new proprietary NAND boot technology, Shark eliminates the requirements for boot ROM. In the past, systems have had to rely on a secondary non-volatile memory device for boot functionality.

Farshid Sabet, SanDisk director of retail product and technical marketing, said, "NAND flash memory is becoming the industry standard for high density, non-volatile memory, and now with Shark, NOR components can be eliminated by transferring boot functionality to NAND flash. Compared to NOR flash, NAND flash memory solutions offer higher chip densities, operate at significantly improved write performance levels, consume substantially less power and have a lower price per megabit. NAND's very small cell size delivers an affordable mass storage solution for consumer electronic products that require write intensive applications and large amounts of data storage for digital music, digital images and data files."

With Shark, designers may use the latest MLC NAND technologies available in higher densities and lower cost than binary NAND flash. Developers can quickly incorporate NAND flash into a system-on-chip with efficiency and ease. Shark bridges NAND flash to high performance interfaces such as ARM's Advanced Microcontroller Bus Architecture™ (AMBA) and Advanced High-performance Bus (AHB). Shark's host interface can also be configured to work with Asynchronous Memory Bus (AMB).

SanDisk offers a complete family of embedded and removable flash development tool kits. The Shark NAND MLC and binary development tool kit is priced at $19,950 and is available immediately. In addition to Shark, the company offers other tool kits including: Stingray; NAND Boot Solution; NAND Host Interface Logic; HDTK (host development tool kit) for Secure Digital™, CompactFlash® and Memory Stick®; and Security SDKS (software developer kits). SanDisk entered the rapidly growing NAND flash memory chip business in 2001 with the introduction of its first NAND devices -- 256 Megabit (Mbit), 512Mbit and 1 Gigabit MLC flash memory chips. The chips, used primarily for data storage, are offered in TSOP and BGA packages and are widely used in a wide variety of consumer electronics products.

SanDisk, the world's largest supplier of flash data storage products, designs, manufactures and markets industry-standard, solid-state data, digital imaging and audio storage products using its patented, high density flash memory and controller technology. SanDisk is based in Sunnyvale, CA.
