Flash-EEPROM in a Router – a true MTD. A Memory Technology Device (MTD) is a type of device file in Linux for interacting with flash memory. The MTD subsystem was created to provide an abstraction layer between the hardware-specific device drivers and higher-level applications. Although character and block device files already existed, their ...
UBIFS (UBI File System, more fully Unsorted Block Image File System) is a flash file system for unmanaged flash memory devices. [1] UBIFS works on top of an UBI (unsorted block image) layer, [2] which is itself on top of a memory technology device (MTD) layer. [3] The file system is developed by Nokia engineers with help of the University of ...
F2FS (Flash-Friendly File System) was added to the Linux kernel 3.8. [10] Instead of being targeted at speaking directly to raw flash devices, F2FS is designed to be used on flash-based storage devices that already include a flash translation layer, such as SD cards. [11]
Memory technology device, a type of device file in Linux for interacting with flash memory; Metadynamics, a computer simulation method in computational physics, chemistry and biology; MTD (mobile network), a former manual mobile network in Sweden, Norway and Denmark
Journalling Flash File System version 2 or JFFS2 is a log-structured file system for use with flash memory devices. [1] It is the successor to JFFS. JFFS2 has been included into the Linux kernel since September 23, 2001, when it was merged into the Linux kernel mainline as part of the kernel version 2.4.10
Linux-based devices or Linux devices are computer appliances that are powered by the Linux kernel and possibly parts of the GNU operating system. Device manufacturers' reasons to use Linux may be various: low cost, security, stability, scalability or customizability. Many original equipment manufacturers use free and open source software to ...
[1] [2] The Linux 4.4 kernel is an example of an operating system kernel that supports open-channel SSDs which follow the NVM Express specification. The interface used by the operating system to access open-channel solid state drives is called LightNVM. [3] [4] [5]
JBD, or journaling block device, is a generic block device journaling layer in the Linux kernel written by Stephen Tweedie from Red Hat. JBD is filesystem-independent. ext3, ext4 and OCFS2 are known to use JBD. [1] [2] JBD exists in two versions, JBD and JBD2. JBD was created with ext3 in 1998. [3]
