NuSMV first tries to read and execute commands from an initialization file if such file exists and is readable unless -s was passed on the command line. File master.nusmvrc is looked for in the directories defined in environment variable NUSMV_LIBRARY_PATH or in the default library path if no such variable is defined. If no such file exists ...
Native Command Queuing was preceded by Parallel ATA's version of Tagged Command Queuing (TCQ). ATA's attempt at integrating TCQ was constrained by the requirement that ATA host bus adapters use ISA bus device protocols to interact with the operating system. The resulting high CPU overhead and negligible performance gain contributed to a lack of ...
Programmable read-only memory (PROM) can be altered once after the memory device is manufactured using a PROM programmer. Programming is often done before the device is installed in its target system, typically an embedded system. The programming is permanent, and further changes require the replacement of the device.
NVM Express over Fabrics (NVMe-oF) is the concept of using a transport protocol over a network to connect remote NVMe devices, contrary to regular NVMe where physical NVMe devices are connected to a PCIe bus either directly or over a PCIe switch to a PCIe bus.
UAS depends on the USB protocol, and uses the standard SCSI command set. Use of UAS generally provides faster transfers compared to the older USB Mass Storage Bulk-Only Transport (BOT) drivers. UAS was introduced as part of the USB 3.0 standard, but can also be used with devices complying with the slower USB 2.0 standard, assuming use of ...
A die allows a single I/O command to be executed at a time. A plane allows similar flash commands to be executed in parallel within a die. There are three fundamental programming constraints that apply to NAND: a write command must always contain enough data to program one (or several) full flash page(s), writes must be sequential within a block,
The install command is a Unix program used to copy files and set file permissions. Some implementations offer to invoke strip while installing executable files. The command is not defined in POSIX. It has mostly split into two camps in terms of compatibility, a GNU type and a BSD type. The main incompatibility lies in the definition of options ...
Also known as "Power-off Retract Count" per conventional HDD terminology. Raw value reports the number of unclean shutdowns, cumulative over the life of an SSD, where an "unclean shutdown" is the removal of power without STANDBY IMMEDIATE as the last command (regardless of PLI activity using capacitor power). Normalized value is always 100. [50 ...
