  2. Memory corruption - Wikipedia

    en.wikipedia.org/wiki/Memory_corruption

    Memory corruption occurs in a computer program when the contents of a memory location are modified due to programmatic behavior that exceeds the intention of the original programmer or program/language constructs; this is termed as violation of memory safety.

  3. ECC memory - Wikipedia

    en.wikipedia.org/wiki/ECC_memory

    A 2010 simulation study showed that, for a web browser, only a small fraction of memory errors caused data corruption, although, as many memory errors are intermittent and correlated, the effects of memory errors were greater than would be expected for independent soft errors. [8]

  4. Soft error - Wikipedia

    en.wikipedia.org/wiki/Soft_error

    Conventional memory layout usually places one bit of many different correction words adjacent on a chip. So, even a multi-cell upset leads to only a number of separate single-bit upsets in multiple correction words, rather than a multi-bit upset in a single correction word.

  5. Memory safety - Wikipedia

    en.wikipedia.org/wiki/Memory_safety

    A guard page typically halts the program, preventing memory corruption, but functions with large stack frames may bypass the page, and kernel code may not have the benefit of guard pages. Heap exhaustion – the program tries to allocate more memory than the amount available. In some languages, this condition must be checked for manually after ...

  6. Dangling pointer - Wikipedia

    en.wikipedia.org/wiki/Dangling_pointer

    If the program writes to memory referenced by a dangling pointer, a silent corruption of unrelated data may result, leading to subtle bugs that can be extremely difficult to find. If the memory has been reallocated to another process, then attempting to dereference the dangling pointer can cause segmentation faults (UNIX, Linux) or general ...

  7. Address space layout randomization - Wikipedia

    en.wikipedia.org/wiki/Address_space_layout...

    Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...

  8. Memory scrubbing - Wikipedia

    en.wikipedia.org/wiki/Memory_scrubbing

    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 ...

  9. Memory timings - Wikipedia

    en.wikipedia.org/wiki/Memory_timings

    Memory timings or RAM timings describe the timing information of a memory module or the onboard LPDDRx. Due to the inherent qualities of VLSI and microelectronics, memory chips require time to fully execute commands. Executing commands too quickly will result in data corruption and results in system instability.
