Flash Memory
The potential of metal-oxide semiconductors (MOS) technology to lead to high density and high performance of the memory devices became known in the mid-1960s. Then, chip makers started thinking hard on how to solve the main problem associated with the MOS memory concept—its volatility.
The Main memory (RAM) is most responsible for handling operating and application needs. Unfortunately, being a volatile memory, RAM loses all data when the system is powered down.
Another type of memory is called ROM, or Read Only Memory. ROM has data permanently stored even when the system is off, and represents a nonvolatile semiconductor memory (NVSM) technology.
The first solutions for the volatility problem came in 1967 in the form of a floating ...
