Outline What is memory. Types of memory. Random access memory. Read only memory. Summary.

What is Memory? Memory is an electronic component that stores data temporarily for rapid retrieval.

Memory Non-volatile Volatile ROM CMOS RAM Flash memory

What is RAM? Consists of memory chips that can be read from and written to by processor and other devices.

Types of RAM DRAM ( Dynamic Random Access Memory ). SRAM ( Static Random Access Memory ).

How does RAM works? The RAM acts as an intermediary between the hard drive and the processor; the hard drive sends data to the RAM necessary for running a given application, and the processor accesses the data saved to the RAM to run the application. As soon as a certain process stops, the data saved the RAM.

What is ROM? Refers to memory chips storing permanent data and instructions.

Types of ROM Firmware. PROM ( Programmable Read Only Memory ). EEPROM ( Electrically Erasable Programmable Read Only Memory ).
