WebMar 24, 2024 · A single integrated circuit (IC) housing the decoder and OR gates make up ROM. A few Read-Only Memory examples are: MROM (masked read-only memory), PROM (programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory), and Flash Memory. WebSep 6, 2024 · Flash Memory is a form of EEPROM invented in the early 1980s. Its key advantages are that it makes chip space more efficient and reprogrammed thousands of times without damage or erasure. Reprogramming can be limited to a portion of the chip rather than the whole thing. The erasure and reprogramming process is much faster, …
WebFeb 7, 2024 · EPROM is a type of erasable ROM that can be adjusted more than once. However, if you want to write new data on an EPROM, you will need a special programmer circuit. EPROMs are designed with a quartz window which enables them to be erased under a powerful UV light.

WebFeb 12, 2024 · EEPROM (Electrically erasable programmable read-only memory) – The data can be erased by applying an electric field, with no need for ultraviolet light. We can erase only portions of the chip. MROM (Mask ROM) – Mask ROM is a kind of read-only memory, that is masked off at the time of production. Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating gate MOSFETs. They … See more Background The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS), also known as the floating-gate transistor.
