Application Space for Non-Volatile Memories

Depending on the application, the technical requirements for the NVM may depend on various aspects ranging from functionality, size of the memory, number of bits, power supply to data retention needs. Modern memory applications often require the parallel integration of several storage architectures in one device.

The table below lists what functionalities the different types of memories are suitable for.
