MEMORY - Coggle Diagram
MEMORY
types of memory
volatile memory
Random Access Memory(RAM)
- called as main memory
- can be read and from and written to by processor
- holds data or programs that are currently being used by the processor
- assembled on a small circuit board called memory module which is plugged onto the memory slots
types of RAM
MAGNETSTORESISTIVE RAM(MRAM)
- Stores data using magnetic charges instead of electrical charges
DYNAMATIC RAM (DRAM)
- Chips must be reenergized constantly
STATIC RAM (SRAM)
- Chips do not have to be reenergized (static) : make it faster than DRAM
- Expensive than DRAM
- Volatile memory loses its content when the power is turned off
- Volatile memory are temporary
- example: Random Access Memory (RAM)
non-volatile memory
TYPES OF ROM
PROGRAMMABLE ROM(PRAM)
- A blank ROM chip which allows programmer to write permanently
ERASEABLE PROGRAMABLE ROM(EPROM)
- Allow programmer to erase the contents by exposing to ultraviolet light
ELECTRICALLY ERASEABLE PROGRAMABLE ROMtext
- Allow programmer to erase the contents with an electrical signal**
READ ONLY MEMORY(ROM)
- Memory chip that sores permanent data a instructions
- Mostly cannot be modified
- Contain a small startup program (bios) which is used to be boat the computer
- Exits as a chip on the motherboard
- Does not lose the contents when the power is turned off
- memory is permanent
- example: Read Only Memory(rom) , Flash memory, CMOS
FUNCTION
To store data and instruction waiting to be executed by the processor and the results of processing the data (information)
DEFINATION
Memory consist of electronic components that store instructions waiting to be executed by the processor
