A blank ROM (Read-Only Memory) that can be programmed once only is typically referred to as PROM (Programmable Read-Only Memory). Once programmed, the data is permanently written and cannot be altered or erased. It is often used in applications where data integrity is crucial and is designed for specific tasks that do not require updates. This makes PROM suitable for firmware storage and similar applications.

A ROM chip that can be programmed once is known as a what?
PROMs can only be programmed once. They are more fragile than ROMs. A jolt of static electricity can easily cause fuses in the PROM to burn out, changing essential bits from 1 to 0.
What is programmed chip?
ROM
What memory is programmed at the time it is manufactured?
rom
A ROM chip that can be programmed over and over using ultraviolet is known as what?
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer.
WHAT is ultraviolet E PROM?
A type of ROM(Read Only Memory) which can be programmed and can be erased after programming using ultraviolet rays.
Does ROM accept new information?
Read-Only Memory (ROM) typically does not accept new information once it has been programmed. It is designed to store permanent data that does not change, such as firmware or system instructions. However, some types of ROM, like EEPROM (Electrically Erasable Programmable Read-Only Memory) or Flash memory, can be rewritten and accept new information under certain conditions.

What does programmable in programmable devices mean?
Programmable devices can be customized by users for their application. Consider the difference between a Read Only Memory (ROM) and a Programmable Read Only Memory (PROM). A ROM is programmed by the manufacturer and delivered to the user. The function of the ROM is the same no matter who uses it. A PROM is a type of ROM that is delivered blank to the user. The user can store a custom program on the PROM to tailor the device for their application. In short, a programmable device can be customized by the user.

What are the disadvantages of ROM?
ROM or "read-only memory" cannot be altered. Once a ROM chip or other ROM media is created, it cannot be changed by user-accessable means and is therefore inflexible.
How do prom and eprom differ from each other?
Ans. Read Only Memory (ROM):Another important part of main memory is Read Only Memory (ROM). Instructions can only be read from ROM. Instructions once written on ROM chip cannot be changed. It is a permanent or non-volatile memory of a computer, i.e. the contents of this type of memory are not lost when the computer is turned off. As soon as the computer is turned on, a program that resides in ROM automatically makes the computer ready for use. ROM is a semiconductor memory generally programmed by the manufacturer.Difference between PROM and EPROM:(Programmable Read Only Memory):It is a non-permanent memory of a computer. It is programmeable read only memory.EPROM (Erasable and programmable Read Only Memory):It is a non-permanent memory of a computer. It is programmeable and erase able read only memory.
