In-Memory Database

What is in-memory technology?

In-memory refers to using a computer’s random access memory (RAM) as opposed to its hard disk drives or flash memory storage. RAM is magnitudes faster than a hard disk drive and therefore software that can run in-memory without having wait to load data from disk can run many times faster that software relying on disk.

Running in-memory means it’s incredibly fast, and when you are trying to analyze large data volumes, in-memory is the way to go.

At a fundamental level, RAM is made up of bits of storage, each bit can be stored using two NOR logic gates wired together and referred to as a “set/reset latch” or “flip-flop” circuit. This type of storage is referred to as volatile as the memory requires power to retain its contents.
