What is a type of chip from which data can be erased by expoure to ultraviolate light?
A type of PROM (Programmable Read-Only Memory) called EPROM (Eraseable Programmable Read-Only Memory) is a chip that, after being programmed, can be exposed to strong ultraviolet light in order to erase it. They're recognized by the transparent window on the top surface through which you can see the silicon chip. It's through this window that UV enters to erase the chip.
How does data get on the microchip after manufacturing?
Well, honey, after the microchip is manufactured, data is typically programmed onto it using specialized equipment that can write and read information to and from the chip. This process is usually done in a controlled environment to ensure accuracy and reliability. So, in a nutshell, data gets on the microchip after manufacturing by writing it onto the chip using fancy machines.
Explain the operation of an EPROM?
Aneprom is a programmable read only memory. It can be reprogrammed many times. Takes ultraviolet rays to erase the EPROM usually minutes However on sun light ultra Violet emission will take years to completely erase it.To program the chip one pin is raised to a hi voltage and whatever data 1/0 on the input will be burned into it where it is determined by the address line. So data will be burned at whatever address is selected. This data will remain embedded until again erased.
How a pen drive store data?
it is what is known as eprom it basicaly stores information by programming a read only chip
A ROM chip that can be programmed over and over using ultraviolet is known as what?
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer.
Will a digital camcorder record over itself on a flash memory chip?
Not by accident. The camcorder will record until there is no more unused memory on the chip, and then will stop recording. If you want to erase the chip and record something else, the camcorder will have a menu or command to format the chip, which will erase all data.
How can be erase data stored in ROM?
A standard ROM or PROM cannot be erased, only erasable PROM can be erased. It is done with either UV light or electronically depending on the type of EPROM.
Which type of data is present in EPROM?
Cannot be universally answered, it depends on the current EPROM. It might be empty as well.
How do you switch and eprom chip on a cadillac deville bcm?
Pull it straight up out of its socket.
Where are post instructions stored?
Power On Self Test instructions are part of the BIOS that is stored in EPROM. Some of the parameters used by the EPROM are stored in the BIOS CMOS chip.
What is EPROM in computer terms?
It stands for Erasable Programmable Read Only Memory. It's basically a computer chip that can have information programmed onto it - which stays on the chip even when the power is turned off (unlike RAM which is erased when you turn the computer off) The EPROM can be re-programmed by erasing the current information and re-writing new information to it.
What is the differencebetween on-chip and off-chip memory?
On-chip memory is a memory that resides on microcontroller itself. e.g RAM. It may be one of the Internal RAM or Special Function Register (SFR). Off-chip memory is external ROM or EPROM.
