Question

An EPROM has a window to allow UV light to enter under certain conditions. The purpose of this is to

a. refresh the data

b. read the data

c. program the IC

d. erase the data

Answer 1

The window on an EPROM is for allowing ultraviolet (UV) light to erase the data so that the chip can be reset and reprogrammed with new data.

Step-by-step explanation:

The EPROM, which stands for Erasable Programmable Read-Only Memory, is a type of memory chip that retains data without power. The window on an EPROM is used for letting in ultraviolet (UV) light to erase the data stored on the chip. This action resets the chip to its initial, unprogrammed state, which allows it to be reprogrammed with new data.

Once the data on an EPROM is erased with UV light, it can be reprogrammed using an EPROM programmer which applies higher voltage to the chip for the reprogramming process.
