6. Random access memory (RAM) is the best
known as computer memory.
It is volatile memory which store current data
& instruction for processing.
RAM is consider as volatile memory, which
means that the stored information is lost when
there is no power.
Whenever you open a program, It gets loaded
from the hard drive into RAM.

7. RAM(Random Access
Memory) was invented by
Robert Heath Dennard.
At IBM Tomas J Watson
research center in 1968.

32. RAM
SRAM(Static
Random access
memory)
DRAM(Dynamic
Random Access
Memory)

33. SRAM(Static Random Access Memory)
SRAM Holds data in a static from, as long as memory has the
power .
Each bit is stored on four transistor that forms two cross
couple inverter .
DRAM(Dynamic Random Access Memory)
DRAM is called dynamic because it must constantly be
refreshed and lose the data vary short time.
DRAM stores each bit of data in a separate capacitor within
integrated circuit.

52. From Beginning :
256MB
512MB
1024MB(1GB)
2048MB(2GB)
4096MB(4GB)
8192MB(8GB)
oNote: Here every time the size of RAM increase by
multiplying twice.

53. ASUS
Buffalo Technology
Century
CEON
CHAINTECH
ELIXIR
HP

54. Program will load much faster.
Power Efficient, that uses much less power than disk
drive
Volatile: A power outage will cause irrecoverable data loss.
Space-limited: Cost per bit is high.

55. Future update version of RAM :
External RAM Enhance Computer Speed
In Computing interface development, In the abbreviation for
the fifth generation of Double Data Rate Synchronous
Dynamic Random Access Memory.
DDR is planned to reduce power consumption once again,
While doubling bandwidth and capacity relative to DDR4
SDRAM.
Type: Synchronous Dynamic Random Access Memory(SDRAM)
Release date: 2019(Estimated)
