Flash memory in dbms
WebJun 9, 2024 · Conversely, NOR Flash offers a lower density and therefore has a lower memory capacity compared to NAND. This makes NOR Flash more appropriate for low-capacity and high-reliability applications, such as storing code in devices including cell phones or medical devices. Additionally, NOR has a larger memory cell size which limits … WebAn in-memory database ( IMDB, or main memory database system ( MMDB) or memory resident database) is a database management system that primarily relies on main memory for computer data storage. It is contrasted with database management systems that employ a disk storage mechanism.

Consider the use of a ramdisk. However, most DBMSs (those with SQL) are not designed to run entirely in memory and put alot of effort to minimize disk IO and paging: a DBMS works very hard to keep the "relevant data" hot (in memory and in cache) -- IO is slow, slow slow.

WebAn in-memory database (IMDB) stores computer data in a computer’s main memory instead of a disk drive to produce quicker response times. Accessing data stored in memory eliminates the time needed to query data from a disk. In-memory databases are used by applications that depend on rapid response times and real-time data management.
