<br>A memory card is an digital data storage device used for storing digital info, typically utilizing flash [Memory Wave App](https://gitlab.and-works.com/theresafolings/memory-wave-workshop4770/-/issues/20). These are generally utilized in digital portable electronic gadgets, Memory Wave corresponding to digital cameras as well as in lots of early video games consoles such because the Neo Geo.

Some had been additionally marketed as a decrease cost different to ROM cartridges. Mitsubishi Melcard which got here in variants using 60 and 50 connector pins.<br>
<br>The Sega Card was developed as a less expensive alternative to recreation cartridges. Some memory cards have been used for Memory Wave memory enlargement in laptops.
