What is a type of ROM that is erased in blocks and currently holds a system's BIOS?
Flash EPROM
Which type of ROM can be erased by UV light?
eprom (erasable programmable read only memory )
What is name of Memory chips erased by ultra violet light?
EPROM (Erasable Programmable Read Only Memory)
Which data will be erased if the power supply is off?
Any unsaved data will be lost when the power is shut off.
How is eprom erased?
EPROM is basicaaly of two types- EEPROM and UVEPROM. EEprom can be ereased by uising electrical pulses, whereas UVEPROM can be ereased by placing the IC in ultravoilet light for atleast 20 minutes.
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.
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.
Can ROM be erased or added to?
No. However there are forms of ROM that can be changed, like Programmable Read Only Memory (PROM) and Erasable Programmable Read Only Memory (EPROM).
What are Erased files on c drive?
Erased files on a c drive are files which have had their locations removed from the file system index. Some operating systems keep a list of erased files in order to track them.
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 difference between PROM and EPROM?
EPROM (Electronic Programmable Read Only Memory) chips can be erased if it needs to be updated or fixed. It can be erased electronically only These are comparatively expensive than PROMs. PROM (Programmable Read Only Memory) chips are relatively once written and to rewrite them you need to replace entire data on it. These are relatively less costly. PROM is the Programmable ROM that allows the user to store data. an instrument called a PROM programmer does the storing by 'burning in', once the data has been burned, the data cannot be erased! On the other hand, an EPROM allows the data to be erased by the help of uv lights. i.e EPROM is uv light erasable and electrically reprogrammable.
What is the meaningful of eprom?
EPROM stands for Erasable Programmable Read Only Memory.
