What is Random Access Memory and how is it use?
Answers
Random Access Memory (RAM) is the internal memory of the CPU for storing data, program, and program result.
RAM is considered volatile memory, which means that the stored information is lost when there is no power.
RAM is of two types
1)Static RAM (SRAM)
2)Dynamic RAM (DRAM)
Static RAM (SRAM)
The word static means it holds the data in a static form as long as power is being supplied.
Information is stored in the form of bits.
SRAM consists of internal flip-flops.
The main characteristic of Static RAM are :
Long life ; faster ; large size ; High power consumption ; Used as Cache memory ; Expensive
Dynamic RAM (DRAM)
Dynamic RAM is a type of memory that is used for data or program code that a computer processor needs to function.
Information is stored in the form of charge.
DRAM consists of MOS transistors and capacitors.
The main characteristics of Dynamic RAM are :
Short data life time ; slower compared to SRAM ; Less power consumption ; used as RAM ; Less expensive.
