NAND Flash memory technology today is available as both SLC (single-level cell)

Question

NAND Flash memory technology today is available as both SLC (single-level cell) or MLC (multi-level cell) devices. In SLC, each cell can be in one of two states, while in MLC the cell can be held in any of four states. How many bits of information can be stored in a word made up of n single-level cells and n multi-level cells respectively, for the cases n = 8, 16, 32. What is the largest unsigned integer that can be stored in a word made up of n single-level cells and n multi-level cells respectively, for the cases n = 8.16. State your answer as exact decimal values.

Explanation / Answer

Bit of information
For SLC:-
n=8:     28=256

n=16:    216=65536

n=32:    232=4294967296

For MLC:-

n=8:     48 = 65536

n=16:   416 = 4294967296

n=32:   432 = 18446744073709551616

Unsigned Integer

SLC: n=8 =256

n=16 = 65536

MLC: n=8= 65536

n=16=4294967296
