128M-BIT VirtualChannel DRAM
TM
MOS INTEGRATED CIRCUIT
Description
The 128M-bit VirtualChannel DRAM is implemented to be 100% pin and package compatible to the industry
standard SDRAM. It uses the same command protocol and interface as SDRAM. It also follows the same electrical
and timing specifications of the SDRAM, such that it is possible for one product platform to be used with the
VirtualChannel DRAM and non-VirtualChannel DRAM part.
