what is the difference between rom prom eprom and eeprom?

PROM is a Read Only Memory (ROM) that can be modified only once by a user while EPROM is a programmable ROM that can be erased and reused. EEPROM, on the other hand, is a user-modifiable ROM that can be erased and reprogrammed repeatedly through a normal electrical voltage.

An ECC memory will automatically detect errors that come from your memory and will automatically correct them. A non-ECC memory won't do it but it does perform a bit faster, and will also be slightly cheaper.

BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.

RAM is a volatile memory which could store the data as long as the power is supplied. ROM is a non-volatile memory which could retain the data even when power is turned off. Data stored in RAM can be retrieved and altered. Data stored in ROM can only be read.

So they are all based on the same chip, the difference between the different versions are fairly small. Mainly the non standard models offer better cooling, and some may offer modified power delivery (meaning you could possibly over clock them further than the stock version).

Both static and dynamic RAM are considered volatile, as their state is lost or reset when power is removed from the system. By contrast, read-only memory (ROM) stores data by permanently enabling or disabling selected transistors, such that the memory cannot be altered.

RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.

ROM is the meaning of Read Only Memory, which means that this memory can only be read and cannot be written. RAM is an abbreviation for Random Access Memory. RAM can be read and written randomly. ... In the mobile phone, RAM refers to the mobile phone memory, which belongs to the internal memory of the mobile phone.

RAM is just memory for programs, data and files. A ram module is normally added to to the internal RAM of the machine. Perhaps a better way to say it is that an EPROM (Erasable Programmable Read-Only Memory) is a non-volatile storage device that does not require any type of standby power to maintain its contents.

RAM equals the memory (or memory bar) of the computer, while ROM is the device's internal storage, equaling the hard disk of the computer. The bigger the RAM, the more software the phone runs smoothly; While the bigger the ROM, the more data it can store.

According to Sematech.org, the most common varieties of these chips used in computers are dynamic RAM (DRAM) chips, while others include Flash, EPROM and EEPROM (which are more often used in cell phones and other handheld devices).

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.

There is one major difference between a read-only memory (ROM) and a random-access memory (RAM) chip: ROM can hold data without power and RAM cannot. Essentially, ROM is meant for permanent storage, and RAM is for temporary storage.

Data in ROM is non-volatile, that is, it remains there even without electrical power. C. ROM provides very large amounts of inexpensive data storage.

Only certain Game Boy Advanced cartridges use a battery backup. A GBA cartridge can contain either EEPROM, SRAM, or Flash RAM. Only the SRAM variant would need a battery backup. So for most games it is not a problem.

A programmable read-only memory (PROM) is a form of digital memory where the setting of each bit is locked by a fuse or antifuse. ... The key difference from a standard ROM is that the data is written into a ROM during manufacture, while with a PROM the data is programmed into them after manufacture.

ROM: Stands for read-only memory. ... Flash memory: A special type of memory that works like both RAM and ROM. You can write information to flash memory, like you can with RAM, but that information isn't erased when the power is off, like it is with ROM.
