MEMORY is a storage engine for MySQL and MariaDB relational database management systems, developed by Oracle and MariaDB. Before the version 4.1 of MySQL it was called Heap. The SHOW ENGINES command describes MEMORY as: Hash based, stored in memory, useful for temporary tables. MEMORY writes table data in-memory.
This means that all connectors, libraries and applications which work with MySQL should also work on MariaDB—whether or not they support its native features. On this basis, Fedora developers replaced MySQL with MariaDB in Fedora 19, out of concerns that Oracle was making MySQL a more closed software project. [ 52 ]
Increasingly, memory-based solutions for the temporary directory or folder are being used, such as "RAM disks" set up in random-access memory or the shared-memory device /dev/shm in Linux. A Flash-based solid-state drive is less suitable as a temporary-storage device for reading and writing due to the asymmetric read/write duration and due to wear.

In computing, a core dump, [a] memory dump, crash dump, storage dump, system dump, or ABEND dump [1] consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated ...
MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [6] is an open-source relational database management system (RDBMS). [6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language.
A memory-mapped file is a segment of virtual memory [1] that has been assigned a direct byte-for-byte correlation with some portion of a file or file-like resource. This resource is typically a file that is physically present on disk, but can also be a device, shared memory object, or other resource that an operating system can reference through a file descriptor.
Dereferencing any of these variables could cause a segmentation fault: dereferencing the null pointer generally will cause a segfault, while reading from the wild pointer may instead result in random data but no segfault, and reading from the dangling pointer may result in valid data for a while, and then random data as it is overwritten.
