compact disc read-only memory (s) (noun)
1. A compact disk that is used with a computer (rather than with an audio system).
2. A large amount of digital information that can be stored and accessed, but it cannot be altered by the user.
3. An optical disk that is physically the same as an audio CD, but contains computer data.

"Storage capacity is about 680 megabytes. CD-ROMs are interchangeable between different types of computers."

electrically alterable read-only memory (s), EAROM (noun)
1. A read-only memory in which selected locations can be reprogrammed for a limited number of times by the application of an electric field; used on IBM computers.
2. A read-only memory which can be reprogrammed electrically in the electric field for a limited number of times, after the entire memory is erased by applying an appropriate electric field.
3. A kind of non-volatile memory used in computers and other electronic devices in order to store small amounts of data that must be saved when the electric power is removed; for example, calibration tables or device configurations.
electrically erasable programmable read-only memory, EEPROM
1. A method of storing data on microchips.

Usually bytes can be erased and reprogrammed individually.

RFID tags that use EEPROM are more expensive than factory programmed tags, where the number is written into the silicon when the chip is made, but they offer more flexibility because the end user can write an ID number to the tag at the time the tag is going to be used.

2. A form of read-only memory which can be electrically erased and reprogrammed.
3. An integrated-circuit memory chip that has an internal switch to permit a user to erase the contents of the chip and to write new contents into it with electrical signals.
electrically erasable read-only memory, EEROM
A form of read-only memory in which the entire contents can be erased electrically and reprogrammed hundreds of time without damaging the device.
electron trapping optical memory (s) (noun), ETOM
A method of erasable optical data storage in which information is stored by visible light, then read by illumination with an infrared source that returns trapped electrons to their ground state.

Erasability is achieved by using a higher infrared level than that which is used in reading.

electronic typewriter, memory typewriter (s) (noun); electronic typewriters, memory typewriters (pl)
1. A typewriter in which the input is provided by an operator, but the output is produced by electronic components.
2. A typewriter that functions with the use of microprocessor technology to provide many of the functions of a word-processing system but which has at most a partial-line visual display.
electrostatic memory tube (s) (noun), electrostatic memory tubes (pl)
An electron tube in which information is stored with electric charges.
