EPROM Meaning and
Definition
-
EPROM stands for Erasable Programmable Read-Only Memory. It is a type of non-volatile memory that retains its stored data even when power is turned off. EPROM is an early form of computer memory that can be electrically programmed and erased through a special process.
EPROM consists of a grid of memory cells, each capable of storing a single bit of data. These cells are made up of a floating-gate transistor, which has an extra insulated layer to store electric charge. When the EPROM is programmed, a high voltage is applied to the transistor, which causes electrons to get trapped in the floating gate. This trapped charge alters the transistor's electrical characteristics and thus represents a binary 1 or 0.
To erase the data stored in an EPROM, it needs to be exposed to ultraviolet (UV) light. The UV light is used to remove the trapped charge from the floating gates, making the EPROM ready for reprogramming. Due to this erasable feature, EPROM was widely used in early computer systems where the ability to change the data was important, such as for firmware updates.
EPROMs have a limited number of erase/write cycles. Therefore, they are often used for storing permanent or semi-permanent data, such as microcode, bootloader, or system initialization routines. The process of programming an EPROM involves desoldering it from the circuit board, exposing it to UV light using a special eraser, and then reprogramming it with a new set of data before reinstalling it.
Overall, EPROM is a type of memory that offers the advantage of being both programmable and erasable, making it a popular choice for certain applications in the early days of computing.
Common Misspellings for EPROM
Etymology of EPROM
The word "EPROM" is an acronym for "Erasable Programmable Read-Only Memory". It was coined in the field of computer memory technology and combines various concepts related to its functionality. The "Erasable" part refers to the fact that EPROM chips can be erased and reprogrammed multiple times, unlike other types of ROMs. The "Programmable" aspect indicates that EPROM chips can be programmed to store and retrieve data. Lastly, "Read-Only Memory" refers to the fact that the data stored in EPROM chips remains intact even when the power is turned off, making it non-volatile memory. Therefore, the term EPROM encapsulates the key characteristics of this specific type of memory technology.
