A data processing apparatus includes a microprocessor which processes data and outputs m bits of data simultaneously and a semiconductor chip module. The module has a plurality of memory chips having data width of n bits data formed on each side of a substrate. The apparatus further includes data lines connected to the microprocessor and the memory chips for slicing m bit data into n bit data and providing the sliced n bit data to each memory chip. The data of a data processing apparatus is transmitted by the microprocessor and the memory chips. The microprocessor outputs an address signal to the memory chips. One group of the memory chips outputs data upper n bits to the microprocessor in …

Why it's free to use
- Filed February 27, 1992 and granted April 23, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 27, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 27, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
