SRAM and flash memory
Which is closest to the typical endurance (number of rewrite cycles) of SLC NAND flash memory?
- AAbout 100
- BAbout 100,000
- CAbout 100 million
Show answer and explanation
Answer: B. About 100,000
SLC endurance is typically about 50,000 to 100,000 cycles, decreasing in the order MLC, TLC and QLC as more bits are stored per cell (TLC is on the order of a few thousand). The main limit is the gradual degradation of the tunnel oxide with each program/erase cycle.
- A. About 100 is far too few for SLC.
- B. Correct. SLC is typically about 100,000 cycles.
- C. About 100 million is far too many for flash memory.
