A snapshot dump (or snap dump) is a memory dump requested by the computer operator or by the running program, after which the program is able to continue. Core dumps are often used to assist in diagnosing and debugging errors in computer programs.
Memory forensics is forensic analysis of a computer's memory dump. Its primary application is investigation of advanced computer attacks which are stealthy enough to avoid leaving data on the computer's hard drive. Consequently, the memory (e.g. RAM) must be analyzed for forensic information.
In computer programming, a dumper is a program which copies data from one source (usually a proprietary format) to another (usually in a more easily accessible format). [1] A dumper is a program that saves data from the computer's memory, usually from a foreign process to a (*.dmp) file. Often the process's memory is dumped automatically to ...
Protection relies upon hardware memory protection and thus overhead is typically not substantial, although it can grow significantly if the program makes heavy use of allocation. [16] Randomization provides only probabilistic protection against memory errors, but can often be easily implemented in existing software by relinking the binary.
Computer memory stores information, such as data and programs, for immediate use in the computer. [2] The term memory is often synonymous with the terms RAM, main memory, or primary storage. Archaic synonyms for main memory include core (for magnetic core memory) and store. [3]
Snapshots of computers' volatile memory (i.e. RAM) can be carved. Memory-dump carving is routinely used in digital forensics, allowing investigators to access ephemeral evidence. Ephemeral evidence includes recently accessed images and Web pages, documents, chats and communications committed via social networks.

In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
