Another type of ROM that has often replaced the PROM is the EPROM or the Erasable Programmable Read-Only Memory. The circuits of ROM are simple. d) Portable devices EPROM was developed by Dov Frohman at Intel in 1971 based on the investigation into faulty integrated circuits where gate connections of the transistors had broken. The disadvantage of the EEPROM is/are ________ View Answer, 6. (medical) range of motion (finance) Return on Margin. With more than 15 … 1 0 obj MROM (Mask-programmed ROM): It is programmed at the factory. An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. The contents of the EPROM are erased by ________ <> d) All of the mentioned EPROM stands for Erasable Programmable Read Only Memory, also a category of non-volatile memory devices which can be programmed and also erased. x��Zmo�6����~���"��P��M�C����^?l���(�q���e����)���.��J��p8��y���z.�����?�|Y=�/�ۗ��N/��}�X��a����}��}xx����x){x~����p���\���a�����w[�Ͽ޿��޲�>̮� |����U��_�������x�/E��6�/�Gq��%��,Lc�8�mvwlwQ�XrᎽ�clv%��@ ��eW�1Vәϗ�4u�Gx'�M�����7��C��"��s�F۾�B��HB)Y.�0�lW���w��� ��!����9��Q��͈_���9N�x!�y��7H�~��a����=��s���[!Â|S�p�E�R8C}���O�a�����������E��z������4sJ2�t����nD�K But, you can build a ROM emulator. 3 0 obj b) False View Answer, 13. EPROM. RAM generally loses its data when power is removed. a) The requirement of different voltages to read, write and store information The main difference between EEPROM and Flash is the type of logic gates that they use. The EPROM chip is placed under UV light for some time, ranging between 5 to 30 minutes, after which this memory can be rewritten. The flash memories find application in ______ (electronics, computing) read-only memory. 4 0 obj An EPROM cell is really an analog device. To practice all areas of Computer Organisation and Architecture. The technology that preceded EPROM did not allow the data to be changed. Flash is a very popular term when it comes to storage media as it is used by portable devices like phones, tablets, and media players. EPROM. The disadvantage of the EPROM chip is _______ c) Pre-required Read Only Memory EPROM (or EPROMs) is used as a program memory and RAM (or RAMs) as a data memory.

This MOSFET has a ‘floating gate’, … If it were digital, we would only have an empty room or a room with one person in it. Though ROM (Read-Only Memory) and PROM (Programmable Read-Only Memory) are inexpensive but changing them over the time adds to cost. c) The low speed of operation View Answer, 3. <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> The ROM chips are mainly used to store _____ a) System files b) Root directories c) Boot files d) Driver files 56. a) System files a) Overcharging the chip RAM temporarily stores the data that have to be processed by CPU currently. a) Cost a) The high cost factor Building a retro micro project can be fun, but using old ultraviolet EPROMS is difficult. c) The inefficient memory mapping schemes used With more than 15 … 1. Building a retro micro project can be fun, but using old ultraviolet EPROMS is difficult. View Answer, 12. Program or data is permanently installed at the time of manufacturing. View Answer, 15. 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. ROM usually have an insufficient ca… View Answer, 11. Sanfoundry Global Education & Learning Series – Computer Organisation and Architecture. endobj View Answer. View Answer, 5. Program or data is permanently installed at the time of manufacturing. The ROM chips are mainly used to store _______ b) False What one could safely say is that a RAM on most days is more prominent than a ROM. <> This set of Computer Organization and Architecture Multiple Choice Questions & Answers (MCQs) focuses on “Read-Only Memory”. EPROM was invented by Dov Frohman in the year 1971 at Intel. The memory is the essential component or circuit of any electronic device that needs to store information. It has 12 address lines Ao – A11, one chip select (CS), one read control signal. c) Exposing the chip to IR rays a) The usage of MOSFET’s over transistors EPROM stands for Erasable Programmable Read Only Memory, also a category of non-volatile memory devices which can be programmed and also erased. b) Flash drives EPROM is an Erasable Programable Read-Only Memory. TI�| Explanation: The EPROM uses an extra transistor where the ground connection is there in the ROM chip. EEPROM is Electrical EPROM, that uses Electrical signals to erase the Program stored. © 2011-2020 Sanfoundry. ROMs are integrated circuits that contain data and most often cannot be altered. A read-only memory (ROM) is a logic circuit that can generate all of the possible minterms of its inputs. 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. c) Speed of operation ROM, on the other hand, is an optical drive primarily made of magnetic tapes. b) The low efficiency Definition of EPROM.
