Memoria flash - SLC - MLC
There are 2 kinds of flash memory which are used in multiple formats such USB key, SSD or SD card
SLC Flash : Single-level cell
MLC Flash : Multi-level cell
The 2 kinds are similar in terms of cell design, but different as final products, with important differences in terms of features.
MLC flash are cheaper since they can store more memory in the same silicon.
SLC flash have better performances in other areas such as speed, reliability, temperature tolerance, number of writes.
SLC Flash memories are recommended for professional applications on embedded systems. Their behavior allow to use them as storage media under different Operating Systems (Windows, Linux ...) replacing the hard disc drive.
MLC Flash Memories are good storage media and cheap..
They can be used for USB Pen, Digital cameras, or MP3 players.
