When using zram as compressed swap space, zram is similar to zswap (Virtual memory compression), which is an in-kernel compressed cache for swap pages rather than a general-purpose RAM disk. In contrast, using zram for swap, like zswap, is a more efficient use of RAM for Linux. That is, the OS can hold more memory pages in compressed swap compared to using the same amount of RAM as application memory or disk cache. This zram feature is said to be beneficial for netbooks and other low-power laptops, virtualization devices, and especially embedded devices, those using flash memory.

ZRAM itself, being deemed stable, was released to mainline on kernel 3.14 (3/30/2014). Fedora has adopted ZRAM swap as standard from 33 onward.
