The basic memory cell in static RAM is ____.
Transistor
Capacitor
Flip flop
None
Flip flop
A static RAM (SRAM) cell is a type of semiconductor memory that uses a bistable latching circuitry, typically implemented as a flip-flop, to store each bit of data. Unlike DRAM, it does not require periodic refreshing as long as power is supplied to the circuit.

The fundamental unit of an SRAM cell consists of a cross-coupled inverter structure (usually 6 transistors, known as 6T SRAM). This configuration forms a flip-flop, which maintains a stable binary state (0 or 1) by feeding the output of one inverter into the input of the other, creating a feedback loop that holds the state indefinitely while power is maintained.
SRAM stores data using the state of a flip-flop circuit.
Static RAM does not require a refresh cycle, making it faster than DRAM.
SRAM cells typically require 6 transistors (6T) per bit.
It is primarily used for CPU cache memory due to its high speed.
High speed (low access time)
No refresh circuitry required
Simple interface
Low density compared to DRAM
High cost per bit
Requires more physical space on the chip
CPU Cache (L1, L2, L3)
Buffer memory in networking equipment
Register files in microprocessors
Option B (Capacitor) is the core storage element for Dynamic RAM (DRAM), which requires constant refreshing to maintain charge.
Option A (Transistor) is a component used within the flip-flop circuit but is not the memory cell itself.
C is correct тАФ The basic memory cell in static RAM is implemented as a flip-flop.
Remember: SRAM = Flip-flop (Fast, High Power) and DRAM = Capacitor (Slow, Low Power, Needs Refresh).
