Conclusion
Semiconductor memories

Semiconductor memories remain a key component in the development of this technology. Their regular structure makes it possible to rapidly develop highly complex circuits that will be used to ramp up production lines in new processes.

The market itself is very demanding for memory products, as they are key elements in many application sectors:

• telecommunications ;

• general public ;

• IT...

As a result, the complexity of memory chips has steadily increased, and will continue to do so in the years to come. Figure 21 shows the evolution of the number of transistors per chip since the 1970s for DRAM memories and microprocessors. It can be seen that this trend has never slackened, with memory...
