Difference between the RAM and ROM: Options RAM ROM Stands for Random Access Memory Read Only memory Definition Random Access Memory or RAM is a form of data storage medium that can be accessed randomly at any time, in any order and from any physical location. RAM (Random Access Memory) is the internal memory of the CPU for storing data, program and program result. Locations that have never been written to have the value of 255. Another example of ROM is EEPROM, which is a programmable ROM used for the computer BIOS, as shown in the picture below. Embedded Systems Memory - Volatile vs Non-Volatile, DRAM vs SRAM, ROM vs PROM vs EPROM vs EEPROM vs Flash, etc Started by stephaneb 2 years ago 7 replies latest reply 1 year ago 1568 views. The code is loaded from the secondary memory devices to DRAM and executes there. Re: EPROM vs RAM Message #3 Posted by kc7gr on 27 Nov 2008, 11:48 p. The main difference between EEPROM and Flash is the type of logic gates that they use. RAM (Random Access Memory) and ROM (Read-only Memory) are the two important memory types found on a computer. EEPROM is similar to flash memory (sometimes called flash EEPROM). Technically a CD-ROM is PROM, since is programmed by the laser in your CD burner "burning" the data into it, but we call it CD-ROM because we're confused human beings :) EPROM is Erasable Programmable Read-Only Memory. Data is stored as a charge on an isolated gate capacitor (“floating. EEPROM (also written E 2 PROM and pronounced "e-e-prom", "double-e-prom" or "e-squared-prom") stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed. The user or manufacturer can write data and programs on it using special ultraviolet rays. The EEPROM can be altered while being used in a logic board by using special power circuits and write pulse generators. EPROM (Erasable programmable read-only memory) – In this type the data in it can be rewritten by removing the chip from the circuit board, exposing it to an ultraviolet light to erase the existing data, and plugging it into a PROM programmer. , VPP = 12 V – On-chip high-voltage “charge pump” in newer chips Erase bits – Byte-byte – Entire chip (“flash”) – One block (typically 32K - 66K bytes) at a time Programming and erasing are a lot slower than reading (milliseconds vs. Nowadays, RAM is seen mainly as the primary memory of computers and other gadgets like smartphones and tablets.
