SRAM and flash memory
In flash memory, what is the scheme that stores 3 bits of information in one memory cell called?
- ASLC
- BMLC
- CTLC
Show answer and explanation
Answer: C. TLC
Depending on the number of bits per cell, schemes are called SLC (1 bit), MLC (2 bits), TLC (3 bits) and QLC (4 bits). More bits per cell means higher capacity and lower cost, but threshold voltages must be distinguished more finely, which is a disadvantage for endurance and speed.
