Read Only Memory (ROM) Video Lecture - Computer Science Engineering (CSE)

wrong read-only memory so what is Rome
Rome stands for read only memory Rome is
non-volatile memory means the data in
Rome is not be deleted automatically
when the power is off
so Rome can store data permanently as it
usual the data cannot be modified as it
right on Rome Rome is not used for
larger memory the example of Rome are
like CD Rome and the computer biochip
are some of the example for Rome types
of from now let's discuss about the
types of wrong there are three types of
Rome the first is P Rome
the second is EP Rome the third is
double EP Rome they are all classified
on the basis of data to be stored on it
circuit diagram of Rome now let's
discuss about circuit diagram a--from
how it is formed here B is known as fuse
point if P is connected to ground then
it stores 0 and if P is not connected to
ground then store 1 hence by fusing the
point of P we can store 1 and 0
simultaneously on Rome P Rome
programmable read-only memory in P Rome
data can be inserted only one time and
hence it cannot be modified to store the
data P is fused to store 1 and if P is
not fused its to 0 P is known as fuse
point the second is EP rome irrigable
programmable read-only memory in EP rome
the data can be modified but for
modification of data you will itis
required this is a picture of EP rome in
this picture you see a hole this hole is
designed to pass UV light this UV light
automatically deleted all the data
inside the
'i'm f it past the third is a EP rome
that is electrically erasable
programmable read-only memory data or
IEP rome can easily modified with the
help of electrical charges only there is
no required of any other you right to
delete the data inside the IEP rome this
type of rome are mostly using bias chip
this is a bias chip using computer thank
