What Difference between programmable read-only memory erasable programmable read-only memory and electrically erasable read-only memory?

i think programmable read-only memory are chips programmed with content that cannot be erased and erasable programmable read-only memory are chips programmed with content that cannot be erased but can be replaced by using electrical devices with strong ultra violet rays


What is EPROM in computer terms?

It stands for Erasable Programmable Read Only Memory. It's basically a computer chip that can have information programmed onto it - which stays on the chip even when the power is turned off (unlike RAM which is erased when you turn the computer off) The EPROM can be re-programmed by erasing the current information and re-writing new information to it.


A is a blank ROM that can be programmed once only.?

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.

WHAT is ultraviolet E PROM?

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.

What is memory reading?

Read Only Memory or ROM, is a type of memory that normally can only be read. As opposed to Random Access Memory or RAM, which can be both read and written.
