TDK Corporation announced today the development of the GBDriver RS2 Series of Serial ATA(SATA) II compatible NAND flash memory controller ICs. Sales are scheduled to begin in May.
The new TDK GBDriver RS2 is a high-speed SATA controller IC that supports high-speed access with an effective speed of 95 MByte/second. It is compatible with SLC(single-level cell) memories with 2 KByte/page and 4 KByte/page structures and MLC(multi-level cell) NAND Flash memories, and can be used to create high-speed SATA storage ranging from 128 MByte to 64 GByte. As a result, the GBDriver RS2 series can be used for a wide range of applications ranging from SATADOM and other embedded storage to audiovisual devices and mobile Internet terminals such as Blu-ray disc players and netbooks. The controllers are available in a 120-pin TQPF package and a 144-pin VFBGA package.
The GBDriver RS2 series perform high-speed control and incorporate powerful error correction capabilities scalable to 15-bit ECC(error correction code) as well as the auto-recovery function(read disturbance countermeasures) and a collateral error prevention function in case of power interruption, both of which are commonly included in the TDK GBDriver series. The design serves to enhance the data reliability of NAND Flash memories.
In addition, the GBDriver RS2 series incorporates an original static wear leveling algorithm that averages the number of times each memory block is erased. This maximizes the rewritable life span of NAND Flash memories. SMART(self-monitoring and analysis reporting technology) data determines the number of times each memory block is erased, facilitating quantitative lifespan management of Flash storage.
The controllers also feature an automated encryption function using AES 128-bit encryption. Data in the NAND Flash memory is encrypted, providing robust security against data tampering and leaks.
TDK will begin launching industrial SATA II solid state drives(SSDs) equipped with the GBDriver RS2 controller starting in May 2009.
