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.
