EPROM(erasable programmable read only memory
It is a type of memory chip that retains its data when its power supply is switched off.
Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source.
RAMI
t is a read write memory which permits the modification of data bits stored in the memory array as well as their retrieval on demand. It is a volatile memory.
POLYMER’S BEHAVIOUR ON PASSING OF CURRENT
PEDOT has holes as majority carriers.Electrons are injected into the film creating an electric field, which makes it conducting.
But slowly due to large voltage application, all holes are combined and PEDOT film becomes non-conducting.
CONCLUSION
It is 10 times denser than current magnetic memories.
Store mega-bit of data in millimeter-square device.
Data can’t be rewritten so suitable for permanent storage.
