# Fast direct access to compressed memory
## Paper-based comparison
https://hardworkar.notion.site/RAM-Compression-7b3e8925086b4e64ae7c036f00b1c7c9
## Existing stuff
#### software
- zswap
- zram
- Hurricane (Helix Software Company)
- quantization?
- Active Memory Expansion
- 842 compression algorithm on POWER7+ chip
- Wilson-Kaplan WKdm algorithm (Apple)
#### hardware
- IBM MXT - dedicated processor for transfers local cache <-> RAM
### Shortcomings???
- Low compression ratios - check this out
- Background I/O
- Increased thrashing - not understandable from wiki
