EPROMS Meaning and
Definition
-
EPROMS (Erasable Programmable Read-Only Memories) are a type of non-volatile computer memory that stores data even when the power supply is disconnected. They are electrically programmable and can be erased and reprogrammed multiple times. EPROMs are widely used in various electronic devices, including microcontrollers, embedded systems, and computer BIOS chips.
EPROMs consist of a grid of memory cells, each capable of storing a binary value of either 0 or 1. These cells are made up of transistors, typically metal-oxide-semiconductor field-effect transistors (MOSFETs). The state of each memory cell is determined by whether or not the floating gate of the transistor is charged. A charged floating gate represents a binary value of 1, while an uncharged gate represents a binary value of 0.
Unlike regular read-only memories (ROMs), EPROMs can be reprogrammed by utilizing ultraviolet (UV) light for erasure. When the EPROM is exposed to UV light for a specified amount of time, the trapped electrons in the floating gate are removed, resetting the memory cells to their default state. Once the memory is erased, it can be reprogrammed using a special device known as a programmer, which supplies the necessary electrical charge to the floating gates.
EPROMs are often used in applications that require firmware or software updates without replacing the entire memory chip. Their reprogrammability and non-volatile nature make them ideal for applications where data integrity and longevity are essential.
