How is a chip programmed?
Every microprocessor chip, from a CPU to the chips on a stick of RAM, will have a firmware on it. This is a special program written as microcode by the chip manufacturer, almost always hard-coded into the chip’s circuitry and not re-programmable once the chip has been produced.
Can ROM chips be reprogrammed?
Read-only memory (ROM) is the least flexible of all memory types because it contains an image that is permanently set at production time and cannot be reprogrammed. ROMs are used in high-volume devices that require no updates or corrections. Many devices also use a ROM to hold boot code.
Which is the one time programmable memory?
silicon semiconductor memory cell which is One Time Programmable (OTP). It is a new technology and device structure invented by eMemory. It is an Erasable Programmable Read Only Memory cell (EPROM), manufactured by a fabrication technology, which is 100\% compatible with that of the conventional logic circuit.
What is the difference between eeprom and flash memory?
Flash uses NAND-type memory, while EEPROM uses NOR type. Flash is block-wise erasable, while EEPROM is byte-wise erasable. Flash is constantly rewritten, while other EEPROMs are seldom rewritten. Flash is used when large amounts are needed, while EEPROM is used when only small amounts are needed.

What does a program consist of?
A program (noun) is executable software that runs on a computer. It is similar to a script, but is often much larger in size and does not require a scripting engine to run. Instead, a program consists of compiled code that can run directly from the computer’s operating system.
How do you reprogram a ROM chip?
A ROM device cannot be programmed by a user. Such devices are mask-programmed by the manufacturer and you have to buy a large amount of them (>10k.. 100k). In this case you have to send the manufacturer a HEX-file with the content you wish to have inside your ROM.
Can proms be reprogrammed?
Standard PROM can only be programmed once. While PROM cannot be erased, two other versions of PROM have been developed that can be erased and reprogrammed. One type is called EPROM, or Erasable Programmable Read-Only Memory.
Which memory is programmed at the time it is manufactured?

Which memory is programmed at the time of manufacturing and Cannot be modified later?
The memory which is programmed at the time of manufacturing and cannot be modified later is called PROM.
How do I reset my EEPROM memory?
Select the “Load Fail-safe Defaults” option on the main BIOS screen and hit the “Enter” key. This will return your BIOS to its default state by resetting the EPROM chip. If a confirmation is needed, hit the “Y” key.
Which memory is faster than EEPROM?
Both EEPROM and flash are subject to the limitation that only bytes in an ‘erased’ state can be written, which means that if the user wants to change only one byte of flash, the entire sector must be erased and re-written. This means that flash memory can wear out faster than EEPROM.
