Que : 1 . The RAM created using bipolar transistors is called :

1. Dynamic RAM
2. Static RAM
3. Permanent RAM
4. DDR RAM
Please Select Ans Options .
Explanation

Option 2 is Correct Answer
Static random-access memory (static RAM or SRAM) is a type of semiconductor memory that uses bistable latching circuitry (flip-flop) to store each bit.
SRAM exhibits data remanence, but it is still volatile in the conventional sense that data is eventually lost when the memory is not powered.
The term static differentiates SRAM from DRAM (dynamic random-access memory) which must be periodically refreshed.
SRAM is faster and more expensive than DRAM.
it is typically used for CPU cache while DRAM is used for a computer′s main memory. Characteristics
Advantages:
Low power consumption
Simplicity – a refresh circuit is not needed
Reliabilityv Disadvantages:
Price
Capacity
