It records memory errors, using the EDAC tracing events. EDAC is a Linux kernel subsystem that handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures.
In 1991, Wang won a judgment against Toshiba and NEC over its patents on SIMMs, based in part on its claim of using a ninth RAM chip for parity. [3] [4] In response, SIMMs with three chips rather than nine separate chips for each bit became popular under the theory they did not infringe.
Memory scrubbing consists of reading from each computer memory location, correcting bit errors (if any) with an error-correcting code , and writing the corrected data back to the same location. [ 1 ] Due to the high integration density of modern computer memory chips , the individual memory cell structures became small enough to be vulnerable ...
These errors include non-recoverable internal system chipset errors, corruption in system memory such as parity and ECC errors, and data corruption detected on system and peripheral buses. On some systems, a computer user can trigger an NMI through hardware and software debugging interfaces and system reset buttons.
In computing, a segmentation fault (often shortened to segfault) or access violation is a fault, or failure condition, raised by hardware with memory protection, notifying an operating system (OS) the software has attempted to access a restricted area of memory (a memory access violation).

Out of memory screen display on system running Linux Mint 9 (kernel 2.6.32) Out of memory (OOM) is an often undesired state of computer operation where no additional memory can be allocated for use by programs or the operating system. Such a system will be unable to load any additional programs, and since many programs may load additional data ...
