Abstract

Solid-state memory devices which retain information once the power supply is switched off are called “nonvolatile” memories. For instance, using standard digital technology, a nonvolatile memory can be implemented by writing permanently the data in the memory array during manufacturing (mask-programmed Read Only Memories, ROM). As an alternative, the user can program the information by blowing fusible links or antifuses, thus changing permanently the cell content (i.e. obtaining a Programmable ROM or PROM). In both cases, the memory array can not be erased, thus making these solutions viable only for a limited number of applications.

Keywords
