CMD640, the CMD Technology Inc product 0640, is an IDE interface chip which has a data corruption bug. The data corruption bug is similar to the bug affecting the contemporaneous PC Tech RZ1000 chipset. Both chipsets were used on a number of motherboards, including those from Intel.

CMD Technology Inc was acquired by Silicon Image Inc. in 2001.
