SRAM and flash memory
Which correctly describes the structure of a typical six-transistor SRAM cell?
- ATwo cross-coupled inverters and two access transistors
- BOne transistor and one capacitor
- CSix floating-gate transistors connected in series
Show answer and explanation
Answer: A. Two cross-coupled inverters and two access transistors
A 6T SRAM cell consists of a latch made of two inverters, each driving the other's input (four transistors), plus two access transistors that control the connection to the bit lines. It retains data without refresh as long as power is applied.
