Unlike traditional PIO/DMA mode, which only uses the rising edge of IDE command signal to
transfer data. UDMA/33 uses both rising edge and falling edge, the data transfer rate is double
of the PIO mode 4 or DMA mode 2.
16.6MB/s x2 = 33MB/s

USB is a 4-pin serial peripheral bus that is capable of cascading low/medium speed peripherals
(less than 10Mbit/s) such as keyboard, mouse, joystick, scanner, printer and modem. With USB,
the traditional complex cables from back panel of your PC can be eliminated.

NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically
improves the memory system’s ability to service multimedia requirements. VCM increases
memory bus efficiency and performance of any DRAM technology by providing a set of fast
static registers between the memory core and I/O pins. Using VCM technology results in
reduced data access latency and reduced power consumption.
