ROM: Read Only Memory, Memory that can only be read, it cannot be rewritten.
RAM: Random Access Memory, it's a kind of memory that can be read and rewritten many times, it loses its information when it loses power.

Why eeprom is better than eprom?
The advantages were "accumulative", so a history of the development of ROM is best to explain them: First came ROM - Read-Only Memory. Unlike RAM, ROM could not be written to but had the advantage that it was non-volatile which means its contents are permanently there, they do not disappear when power is removed. But the contents were put there in the factory, you could not "program" the contents yourself. Then came PROM - Programmable ROM. With PROM you could, if you owned a programming machine or "programmer", set the contents of the PROM yourself, one time, before your put it in the electronic circuit board. Next came EPROM - Eraseable PROM - with EPROM if you needed too you could take the EPROM out of the circuit board, put it in an EPROM eraser to reset the contents, and then program it again in the programmer. The EPROM eraser was a small box that the EPROM was placed inside. When the box was turned on ultra-violet light shined into the EPROM thorough a small "window" on the top of each EPROM, erasing the contents. Finally came EEPROM or E2PROM - Electronically Erasable PROM. With EEPROM you didn't need the eraser or the programmer! The EEPROM can be programmed, again and again while it is on the circuit board, by sending a sequence of signals to certain pins on the device.
Which type of ram and rom is being used in Intel computer?
sram and eeprom
Is flash memory a RAM or ROM?
we can say its a kind of ROM... since flash memory is a specialised EEPROM...
What are examples of primary memory?
examples of primary memory are RAM, ROM, PROM, EPROM , etc.....
What are the 2 main types of ROM called?
PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory)
Does n64 GoldenEye cartridge use sram or a eprom?
It does NOT use a Volatile(or battery-packed) save. I don't know whether it uses EEPROM or Flash Ram, but both will last forever.
I have good memory i can read but i can't write?
perhaps you mean ROM, but your question is unclear. not all computers have ROM. some ROM is indeed writable (e.g. PROM, UVPROM, EPROM, EEPROM, Flash ROM), but writing is much slower than reading and often requires nonstandard voltages not normally available in the operating computer. early ROM technologies even required physical rewiring of their circuits to change their contents... but it could be changed.
What is rom define its types?
ROM: Read Only Memory. Rom is memory that normally can only be read, but not written to. Types of ROM: 1. ROM: Basic, hard-coded ROM that has its data implanted at the time of manufacture. 2. PROM- Programmable ROM: Usually is manufactured as blank ROM, and can be written to 1-time by 'burning' fuse links inside the device. 3. EPROM- Erasable Programmable ROM: A PROM device that can be erased through some means. This term is not generally used, as a more-specific method of erasing is usually part of the acronym (See EEPROM and MPROM below). A chip that can be erased by applying light to a window may use this term. 4. EEPROM- Electronically Erasable Programmable ROM: This indicates that the ROM device is erasable through an electronic signal, applied to an "Erase" input. When the correct logic signal (high or low depends on manufacture of the device), the device is "erased" back to it's default state. 5. MPROM- Magnetically Erasable Programmable ROM: This is similar to an EEPROM, except that the device is erased by exposing it to a magnetic field. Another use of the term 'ROM' is CD-ROM (or DVD-ROM). This is a removable media format that is contained on an optical disk. As these discs can only be written to once, they are considered to be Read-only memory. (Note that "rewritable" disks exist...they are commonly designated as "CD-RW" and "DVD-RAM" or "DVD-RW") and would be similar to an EPROM in application.
Which memory does not require programming equipment?
EEPROM
What is the differencebetween on-chip and off-chip memory?
On-chip memory is a memory that resides on microcontroller itself. e.g RAM. It may be one of the Internal RAM or Special Function Register (SFR). Off-chip memory is external ROM or EPROM.
What is ROM eprom eeprom ram?
Here ya go found this on the Internet for you: Acronym for erasable programmable read-only memory, and pronounced ee-prom, EPROM is a special type of memory that retains its contents until it is exposed to ultraviolet light. The ultraviolet light clears its contents, making it possible to reprogram the memory. To write to and erase an EPROM, you need a special device called a PROMprogrammer or PROM burner. An EPROM differs from a PROM in that a PROM can be written to only once and cannot be erased. EPROMs are used widely in personal computers because they enable the manufacturer to change the contents of the PROM before the computer is actually shipped. This means that bugs can be removed and new versions installed shortly before delivery.
Ferroelectric ram as both ram and rom?
only rom
