ROM chips are designed to hold instructions for the computer to perform when it's first switched on. This includes important operations such as...
Check the computer's components are working
Start the hard drive spinning
Read the operating system into RAM
That's just a few of the most important tasks. RAM chips lose their information when the computer is switched off. ROM chips are semi-permanent - meaning the data they hold cannot be erased or over-written easily.
ROM Chips. Read Only Memory.
ROM chips are found not only in computers; many appliances and even toys contain ROM chips. toys contain ROM chips.
They are called eproms or eeproms
Read Only Memory(ROM) Basic Input Output System(BIOS) or firmware chips are "Electrically Erasable and Programmable Read Only Memory(EEPROM)" chips, these kind of chips can be upgraded by flashing.
ROM chips.
Programs stored on ROM chips are called firmware. The motherboard stores the keyboard controller support program on the ROM chip.
There are devices which can write to EPRROM chips <blanks, or unprogrammed chips> that will be able to "flash" or "cook" the ram chip with it's initial load, then it's hard written on there. Will not be able to be changed again under most circumstances. In the strict sense, a true ROM chip is manufactured with the data on it and is unable to be changed at all.
It is 16.
chips with memories are worrying. don't eat them or they will lose their memory!
ROM is Read Only Memory. Normally, data is fabricated into the ROM chips by the semiconductor manufacturer. Special mask(s) have to be made to store this data. Besides ROM chips there are PROM chips, where P stands for Programmable. In these chips, data can be stored by the end user. EPROM is Erasable PROM. A new type of ROM is OTP ROM (One Time Programmable).
You cant
Flash memory and Rom I think
