SRAM and flash memory

How many bits does an SLC (single-level cell) flash memory store per cell?

  1. A2 bits
  2. B4 bits
  3. C1 bit
Show answer and explanation

Answer: C. 1 bit

SLC stores 1 bit (two states) per cell. MLC stores 2 bits, TLC 3 bits and QLC 4 bits. Because SLC states are easy to distinguish, it is fast and has high endurance, but its capacity for the same number of cells is the smallest.

  • A. Two bits per cell is MLC.
  • B. Four bits per cell is QLC.
  • C. Correct. SLC stores one bit per cell.
