MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The ROM programmed during manufacturing process itself is called MROM. Data is stored by the manufacturer during fabrication and user can not alter this data.

Detailed explanation-2: -ROM is programmed during the manufacturing process. ROM refers to computer memory chips containing permanent or semi-permanent data.

Detailed explanation-3: -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.

Detailed explanation-4: -ROM may sometimes be called maskROM (MROM). MROM is a form of read-only memory that is static and programmed into an included circuit by the manufacturer.

Detailed explanation-5: -EEPROMs are the modern type of ROM, electrically erasable via the use of flashing programs. A Programmable Logic Device (PLD) is a field-programmable device, which means it is programmed after it leaves the factory. EPROMs, EEPROMS, and Flash Memory are examples of PLDs.
