What is masked ROM?
Mask ROM is a read-only memory whose contents are programmed by the integrated circuit manufacturer (rather than by the user). … It is common practice to use rewritable non-volatile memory – such as UV-EPROM or EEPROM – for the development phase of a project, and to switch to mask ROM when the code has been finalized.
Which is bigger RAM or ROM?
A ROM chip stores several MB (megabytes) of data, usually 4 to 8 MB per chip, whereas a RAM chip can store multiple GB (gigabytes) of data, ranging from 1 to 256 GB per chip.
Why do we need RAM and ROM?
RAM is the memory available for the operating system, programs and processes to use when the computer is running. ROM is the memory that comes with your computer that is pre-written to hold the instructions for booting-up the computer. RAM requires a flow of electricity to retain data (e.g. the computer powered on).
