c) The usage of an extra transistor Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices.Data stored in ROM cannot be electronically modified after the manufacture of the memory device.Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.Software applications (like video games) for programmable devices … MROM (Mask-programmed ROM): It is programmed at the factory. PROM is a type of ROM that can be programmed only once by a special device and uses high voltages. To overcome this EPROM were introduced. ROM: Read Only Memory. The contents of the EPROM are erased by ________ EPROM is the abbreviation of Erasable Programmable ROM, which means the ROM can be erased and reprogrammed to accomplish a new set of tasks.. zjƖ=}�C�䀄�?g(���FiA�rdsZ��X����QF�ek U�e��)�KU�e���L����w��6�T�D$?m2 �w>�������+=-�07c� TBB9Ɔ�疱�K�6[�|��1�06Z#�F"�ʑ�>rPf�r�O8=n~�����(-_�k[��|ZM��H\M�E*~�z(��*�y�TM.E��R�&Ĩ>?H�"��[0���_�? This light burns out all the tiny charges in the EPROM to reopen its circuits. Decades back RAM has a capacity of 128MB or 512 MB. So let’s sort out the acronyms first: * ROM - Read-Only-Memory - you can read from it but you can’t ever change it. ROM - programme written when manufactured PROM - programmed after manufacture EPROM - erased with UV light EEPROM - erased electrically. Read only memory is very useful for storing any kind of software that is hardly changed during the computer’s system life. RAM mostly looks like a greenish rectangular chip with multiple Integrated Circuits ( ICs ) o nit with teeth to be inserted into the RAM slots. The disadvantage of the EEPROM is/are ________ a) Cost Key Difference between RAM and ROM. EPROM, is Erasable PROM that can be erased by exposing to UV light by removing the mask on the surface of the IC. 1 0 obj The only difference between the EEPROM and flash memory is that the latter doesn’t allow bulk data to be written. While the “electrically erasable” part of EEPROMs name might seem like a throwaway phrase, don’t confuse this type of memory with“EPROM,” which stands for Erasable Programmable Read-Only Memory. The memory devices which are similar to EEPROM but differ in the cost effectiveness is ______ But, you can build a ROM emulator. It stores instructions which are only erased by exposing the memory to ultraviolet light. d) Programmed Read Only Memory View Answer, 7. ROM stands for read only memory EPROM stands for erasable programmable read - only memory DIFFERENCE Difference between these two lies in the possibility of modification of their contents. <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> a) The absence of any movable parts All Rights Reserved.

ROM, which stands for Read Only Memory, stores the instructions required to start a computer. Unlike the other types of media, manufacturers use Random Access Memory (RAM) to The key difference between RAM and ROM is that RAM is basically a read-write memory whereas, ROM is a read only memory. a) True This is due to the high stress condition caused by a write. View Answer, 13. View Answer, 15. If it were digital, we would only have an empty room or a room with one person in it. Read-only memory (ROM) is similar in design to static or dynamic RAM circuits, except that the “latching” mechanism is made for one-time (or limited) operation. electrically erasable programmable read-only memory can be removed and re-programmed. d) Driver files The simplest type of ROM is that which uses tiny “fuses” which can be selectively blown or left alone to represent the two binary states.
