SonyMemory Stick PRO-HG Duo memory card : SanDisk Corporation and Sony Corporation today announced the development of the Memory Stick PRO-HG format expanded from the Memory Stick PRO format. The continuing increase in the capacity of IC recording media has broadened its usage as a practical way to store high-resolution digital photos, music and video content (from the Internet or TV programs) on portable devices that are designed to handle digital entertainment content. The demand for real-time recording and transfer of multiple gigabytes of data using IC recording media is expected to increase rapidly, due to the growing popularity of high resolution video and digital still image applications.

Memory Stick PRO-HG media offers high performance to meet the stringent demands of end users. This new media format uses an enhanced, 8-bit parallel interface in addition to a conventional serial and 4-bit parallel interface. The interface clock frequency also increases to 60MHz from 40MHz. This means that maximum data transfer speed increases up to 480Mbps, or 60MB/s (theoretical value), three times as fast as that of Memory Stick PRO media. The minimum write speed at 8-bit parallel transfer is 120 Mbps, or 15MB/s (In the case of optimized compliant host devices).

These enhancements allow large data amounts of up to several gigabytes to be quickly transferred, as well as the real-time recording of high-resolution video and still images. Since Memory Stick PRO-HG is an extended format of the Memory Stick PRO format, Memory Stick PRO-HG compliant host devices support the conventional Memory Stick PRO media as well as Memory Stick PRO-HG media. In addition, the Memory Stick PRO HG media can be used conventional Memory Stick PRO compliant host devices as well as Memory Stick PRO-HG compliant host devices (When using Memory Stick PRO-HG media with Memory Stick PRO compliant host devices, Memory Stick PRO-HG media functions as Memory Stick PRO). Licensing for the development of Memory Stick PRO-HG compliant host devices is scheduled to commence in January 2007.
