Memory cards were initiated around 1990 when technology in mobile phones and digital cameras commenced to evolve and become more multifarious. Now its not strange to have a mobile phone with a built-in camera of 5 mega pixels which allows you to capture photos of big resolution. As integral storage on phones is very little, on average around 10MB, the requirement for extra storage came about and so the memory card, the SDcard was one of the first.

Whilst the SDcard was the first to be initiated this was rapidly followed by the MiniSD, MicroSD, the MS Micro2 and the Micro SDHC. One of the primary manufacturers to jump on the bandwagon with the requirement for memory was SanDisk, although many others have followed. Not only were they used in phones, cameras and camcorders they were also taken benefit of by those using video games controllers on the likes of the Xbox, GameCube and Play station.

Memory cards vary from 512MB to a massive 8GB which is typically put to good use in the high end digital camera range. SanDisk manufacture an 8GB memory stick M2 which many of the new slim Sony Ericsson phones use. With multi-media phones having high resolution cameras, then large quantity of memory for storage is vital. The beauty of the M2 is that it is compatible with devices that use the memory stick PRO Duo with the use of an M2 adapter. The memory stick M2 also comes in storage of 1GB, 2GB and 4GB.

The Pro duo memory is utilized in the likes of consoles such as the Play station 3, Sony PSP, digital camera such as Sonys Cybershot and several of the many Sony Ericsson phones. The microSD cards are utilized in some of the smaller mobile phones and many come with a special USB adapter, this makes transferring media to and from your device quick and easy. The MicroSDHC memory cards are used in most of Blackberry phones and the smart phones such as from HTC, LG and Nokia. These are generally either 4GB or 8GB and are used to save a range of multimedia such as music, video and high quality photographs.
