- RAM is a temporary storage device.it is also called volatile memory.
- It is a inside the CPU and store the data and program.
- RAM is a one integrated circuit that allow the store data and program.When you system is shout down than memory clean.
- RAM is a random access memory and is the basic kind of internal memory.
- RAM is called "random access" because the processor or computer can use any location or data in main memory.
- RAM has been made from reed relays ,transistors,integrated circuit ,magnetic core, or anything that can hold and store binary value.
- Most morden RAM is made from integrated circuits.
Main two categories of RAM:
1.SRAM:
2.DRAM:
1.SRAM:
- SRAM stand for static random access memory.
- Static RAM is called static because when power is immediately off than information and data is store and hold any location.
- Magnetic core and reed relays are example of static memory.
- SRAM is also used the cache memory and and fast execute or access.
- SRAM is a very expensive.
- SRAM is a no need to refresh because it is auto refresh.
- SRAM is size is very large.
2.DRAM:
- DRAM stand for dynamic random access memory.
- DRAM is called dynamic because when power is off than loss the all data and file.
- Transistors and integrated circuit are example of dynamic memory.
- It is possible to battry backup for device.
- It is a very slow to compare to SRAM.
- DRAM is a need to manual refresh.
- DRAM is used to ram.
- DRAM is a less expensive.
- Less size compare to SRAM.
Type of RAM:
- DIP (Dual inline memory);
- SIPP (Single inline pinned package)
- SIMM (Single inline memory module)
- DIMM (dual inline memory module)
- SRAM (Static random access memory)
- DRAM (Dynamic random access memory)
- SLDRAM (Synchronous link DRAM)
