Abstract
A dynamic, virtually nonvolatile random access memory (RAM) storage cell is provided by storing information in a Nonvolatile Charge Injection Device (NOVCID), first in volatile form, then by an electric signal transferring the stored intelligence into a nonvolatile form from which it may late be recovered. Since only on external command is the information transferred into the nonvolatile storage mode, the memory is described as a virtually nonvolatile RAM.
