The amount of data that can be stored on the microchip in an RFID tag.

Greek: Mnemosyne (goddess)
Latin:(no equivalent)

In technical usage: that part of a computer's memory where information is kept so the computer can find it faster: The new desktop computer has more than two megabytes of cache memory.

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."

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.

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.

A form of read-only memory in which the entire contents can be erased electrically and reprogrammed hundreds of time without damaging the device.

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.

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.

An electron tube in which information is stored with electric charges.

1. An instrument in which information is stored as electrostatic charges on a dielectric surface (insulating material or a very poor conductor of electric current, but an efficient supporter of electrostatic fields).
2. A storage in which information is kept as the presence or absence of electrostatic charges at specific spot locations, generally on the screen of a special type of cathode-ray tube known as a storage tube.
3. The storage of changeable information in the form of charged or uncharged areas usually on the screen of a cathode-ray tube.
4. A memory which stores information in the form of the presence or absence of electrostatic charges at specific locations; such as, on the screen of a special cathode-ray tube known as a storage tube or cells of dynamic random-access memories.

Memory on the microchip in an RFID tag is usually divided into sections, which can be read or written to individually.

Some blocks might be locked, so data can't be overwritten, while others are not.

Random Access Memory memory

General memory for anything significant or having meaning, including words, facts, and ideas.
