Tokyo, Apr 22, 2011 - (JCN Newswire - MySolutionInfo) - TDK Corporation announced today the development of the GBDriver RS3 series of Serial ATA (SATA) 3 Gbps compatible NAND flash memory controller ICs. Sales are scheduled to begin in July.

The new TDK GBDriver RS3 series are high-speed SATA controller ICs that support high-speed access with an effective speed of 170 Mbyte/second. In addition to the existing 2 Kbyte/page and 4 Kbyte/page structures, they support the latest 8 Kbyte/page SLC (single-level cell) and MLC (multi-level cell) NAND flash memories and can realize high-speed SATA storage ranging from 128 Mbyte to 128 Gbyte. As a result, the GBDriver RS3 series can be used for a wide range of applications from SATADOM[1] other embedded storage to mobile internet devices such as smart phones or audiovisual devices such as smart televisions and Blu-ray disc players. The controllers are available in a 120-pin TQPF package and a 144-pin VFBGA package.

The GBDriver RS3 series controllers perform high-speed control and incorporate powerful error correction capabilities up to 44-bit ECC (error correction code) as well as an auto-recovery function (read disturbance countermeasures) and a collateral error prevention function in case of power fail, common features of the TDK GBDriver series. The design serves to ensure extremely high data reliability of NAND flash memories.

In addition, the new GBDriver RS3 series features data randomizer and auto-refresh functions, which are essential for controlling the latest flash memories, to provide sufficient flexibility for future flash developments.

The GBDriver RS3 series also incorporates an advanced static wear leveling algorithm that averages the number of times each memory block is rewritten (erased). This maximizes the life span of NAND flash memories. SMART (self-monitoring and analysis reporting technology) data determines the number of times each memory block is rewritten (erased), facilitating quantitative lifespan management of flash storage.

Data security has also been enhanced. The controllers feature an automated encryption function using AES128-bit[2] encryption. Data in the NAND Flash memory is encrypted, providing robust security against data tampering and leaks.

TDK will launch CFast(TM) compact flash drives and solid state drives (SSDs) equipped with GBDriver RS3 controllers starting in late July.
