Definition of "EEPROM" |
Electrically erasable programmable read-only memory / or an Electrically Erasable PROM is the same as an EPROM except that an EEPROM may be erased via an electric field, hence the term Electrically Erasable. Because these devices are erased via a voltage and not light they do not require a window like EPROMs do. A Flash EPROM is about the same as an EEPROM but does not require an addition special voltage to be erased, and may be erased all at once and not on a byte bases. Memory]. Read more; EEPROM Definition. / Electrically Erasable Programmable Read-Only Memory, electronic erasable programmable read-only memory / Electrically erasable programmable read only memory is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified. However, an EEPROM chip has to be erased and reprogrammed in its entirety, not selectively. It also has a limited life - that is, the number of times it can be reprogrammed is limited to tens or hundreds of thousands of times. In an EEPROM that is frequently reprogrammed while the computer is in use, the life of the EEPROM can be an important design consideration. / EEPROM (also written E2PROM) stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g. calibration tables or device configuration.Unlike bytes in most other kinds of non-volatile memory, individual bytes in a traditional EEPROM can be independently read, erased, and re-written.When larger amounts of static data are to be stored a specific type of EEPROM such as flash memory is more economical than traditional EEPROM devices. EEPROMs are organized as arrays of floating-gate transistors. / See electronically erasable programmable read-only memory. |
