Zeev,

There are probably no important semiconductor products that don't infringe on other patents.

Some examples are:

SGI holds a patent which covers all graphics texture caches. It is impossible to build a graphics chip which does not infringe upon this patent.

MIPS holds a patent which covers all misaligned loads and stores. It is nearly impossible to build a CPU which does not infringe upon this patent.

STM holds a patent which covers all on-chip processor memory (caches, etc.) It is impossible to build a CPU which does not infringe upon this patent.

Most big companies hold large patent portfolios to protect against litigation. DRAM manufacturers are no exception.
