Arasan's ONFI 2.2 NAND Flash Controllers for handheld electronic devices

Arasan has made available NAND Flash Controllers supporting the new Open NAND Flash Interface (ONFI) 2.2 specification, and suitable for cell phones, consumer electronics to netbooks applications.

Arasan's NAND Flash Controller handles raw error bit rates as NAND memory migrates to finer process geometries by processing information contained in the Extended ECC Information data structure stored in NAND memory. In addition, the controller supports booting directly from NAND memory. The IP core is easily implemented using a generic standard cell based flow combined with delay components that are part of a typical ASIC cell library. By integrating Arasan's NAND Flash Controller, SoC designers can interface to a variety of NAND memory devices via a standard ONFI interface.

"SoC designers would like to exploit advances in NAND memory technology without having to develop proprietary interfaces, thereby ensuring compatibility," said Prakash Kamath, Vice-President of Engineering at Arasan. "With Arasan's NAND Flash Controllers, designers can seamlessly interface to any ONFI 2.2 compliant memory, independent of the underlying NAND memory technology."

"Consumer and mobile device manufacturers are constantly exploring options to reduce the cost of their system solutions, particularly memory components," said Somnath Viswanath, Product Marketing Manager at Arasan. "By integrating Arasan's NAND Flash Controller, they now have the option to integrate the most cost effective ONFI based memory over the life of the host processor."

Arasan's NAND Flash Controller supports the transfer modes up to 166MBps (Sync mode 4) and 200MBps (Sync mode 5). The IP incorporate 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 controller can stop the clock during writes to save power.

Arasan provides a "Total IP Solution" for its NAND Flash Controller IP core consisting of RTL source code, synthesis scripts, test environment and documentation.
