Best Way To Increase RAM On Your Android Phone | 2023
90What is ZRAM: zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk. The two most common uses for zram are for the storage of temporary files (/tmp) and as a swap device. Initially, zram had only the latter function, hence the original name "compcache" ("compressed cache")
What is zram used for?: Android uses ZRAM ('Z' in Unix terms is a symbol for compressed RAM). ZRAM swap can increase the amount of memory available in the system by compressing memory pages and putting them in dynamically allocated swap area of memory.
Where is zram stored?: The zram module creates RAM-based block devices, Pages written to these disks are compressed and stored in memory itself.
