EEPROM was developed by George Perlogos at Intel in 1978 based on the previously developed EPROM Technology. • EPROMs have to be erased with exposure to UV light and EEPROMs can be erased electronically. So, the main difference between PROM and EPROM is that the PROM can be programmed just once means that it can be written only one time whereas EPROM is erasable; hence it can be reprogrammed or rewritten. The ROM stores the necessary instruction required for booting up the device or the program code for the device. The ROM process is the simplest of all memory processes, usually requiring only one layer of polysilicon and one layer of metal. Like EPROM, EEPROM can be erased and reprogram, but the difference lies in how the content in both are erased. Laptop RAM is 2.5-3.5 inches long and 1 inch wide.

ROM, EPROM, & EEPROM Technology 9-8 INTEGRATED CIRCUIT ENGINEERING CORPORATION EPROM (Erasable Programmable Read Only Memory) was a great invention that allowed hardware programmers to make changes to their code without buying new chips. The data on most ROM chips cannot be modified — hence, the name readonly. In order to simplify the whole thing, individual bytes are grouped into a smaller number of blocks, which can have thousands of bytes in each block. The technology that preceded EPROM did not allow the data to be changed. Call +91-9892765007. PROM(Programmable Read-Only Memory): EPROM(Erasable and Programmable Read-Only Memory): EEPROM(Electrical Erasable and Programmable Read-Only Memory): PROM is is a type of ROM that can be modified only once by a user. It’s memory is written just the once and programmed electrically by the user at the time or when the initial chip fabrication. In brief, EEPROM is commonly used than PROM and EPROM. EEPROM is the modern version of EPROM. EEPROM (also E 2 PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed. • PROM is the older technology while both PROM and EPROM are nonvolatile memory devices. Although there are some modified versions of programmable ROM such as PROM, EPROM and EEPROM (refer to the article “Types of memory”) that can be reprogrammed several hundred times using special devices. Difference between Priority Inversion and Priority Inheritance. EEPROM (Electrically Erasable Programmable Read-Only Memory) is quite different, it is a memory which is designed to be reprogrammed more frequenty, for example the BIOS configuration settings. Like EPROM, EEPROM can be erased and reprogram, but the difference lies in how the content in both are erased. If there’s miscalculation or error or bug while writing on PROM, it becomes unusable. PROM is totally sheathed during a plastic cowl. 5. Erasable and Programmable Read-Only Memory (EPROM) EPROM can be erased by exposing it to ultraviolet rays for about 40 minutes. The main distinction between PROM and EPROM is that, PROM may be programmed just the once implies that it may be written only 1 time whereas EPROM is erasable; therefore it may be reprogrammed. It is a type of memory which can only be modified once not again and again. If you want to update the Firmware on your BIOS, you can, but the old version of the firmware will be overwritten with the new one. It is second only to magnetic hard drive or SSD in terms of memory storage capacity. EPROM can be reprogrammed by erasing the content on it using electricity.
