On December 11, 2006, Sony, together with [[SanDisk]], announced the '''Memory Stick PRO-HG Duo'''. While only serial and 4-bit parallel interfaces are supported in the Memory Stick PRO format, an 8-bit parallel interface was added to the Memory Stick PRO-HG format. Also, the maximum interface clock frequency was increased from 40&nbsp;MHz to 60&nbsp;MHz. With these enhancements, a theoretical transfer rate of 480&nbsp;Mbit/s (60&nbsp;MB/s) is achieved, which is three times faster than the Memory Stick PRO format.
