Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...
Due to this crystal structure and how it is influenced, F-RAM offers distinct properties from other nonvolatile memory options, including extremely high, although not infinite, endurance (exceeding 10 16 read/write cycles for 3.3 V devices), ultra-low power consumption (since F-RAM does not require a charge pump like other non-volatile memories ...
The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager. [4] Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality.
Linux Intel published an NVM Express driver for Linux on 3 March 2011, [83] [84] [85] which was merged into the Linux kernel mainline on 18 January 2012 and released as part of version 3.3 of the Linux kernel on 19 March 2012. [86] Linux kernel supports NVMe Host Memory Buffer [87] from version 4.13.1 [88] with default maximum size 128 MB. [89]
A NVDIMM (pronounced "en-vee-dimm") or non-volatile DIMM is a type of persistent random-access memory for computers using widely used DIMM form-factors. Non-volatile memory is memory that retains its contents even when electrical power is removed, for example from an unexpected power loss, system crash, or normal shutdown.
apt-cdrom can specify a folder other than a CD-ROM, using the -d option (i.e. a hard disk or a USB keydrive). The Debian CDs available for download contain Debian repositories. This allows non-networked machines to be upgraded. One can also use apt-zip. Problems may appear when several sources offer the same package(s).
This behavior can be overridden using vgconvert --pvmetadatacopies. If the LVM can not read a proper header using the first copy, it will check the end of the volume for a backup header. Most Linux distributions keep a running backup in /etc/lvm/backup, which enables manual rewriting of a corrupted LVM head using the vgcfgrestore command.
The AVR Dragon can both program and debug since the 32 KB limitation was removed in AVR Studio 4.18, and the JTAGICE mkII is capable of both programming and debugging the processor. The processor can also be programmed through USB from a Windows or Linux host, using the USB "Device Firmware Update" protocols.
