Memory cards are responsible in shrinking the world of entertainment to your phone, digital cameras and other portable devices.Let us look at some of the different types of memory cards:

1. Memory Stick: The 2.8 mm Memory Stick, the removable flash memory card, was created by Sony in 1998. It then gave way to an upgrade known as Memory Stick Pro that has more storage capacity and fast data transfer capability.

2. Memory Stick Duo: This 1.6mm card fulfilled the need for Sony to have a smaller memory card for pocket sized cell phones, digital cameras and the Sony PSP.

3. Memory Stick Micro M2: Sony joined hands with SanDisk in 2005 to come up with a Memory Stick that measures 1.2 mm and could store 32 GB data with a transfer speed of 160 MB per second.

4. Multi Media Card: SanDisk and Siemens came up with Multi Media Card in 1997, the smallest card ever measuring 1.5mm. Compared to other memory cards, the MMC had slow data transfer speed, just 2. 5 Megabytes per second. So they came up with a performance enhanced MMC in 2005, called MMCplus. This one has a good data speed of 52 MB per second.

5. Reduced Size Multi Media Card: This 1.5 mm card was introduced by MMCA (Multi Media Card Association), designed specifically for mobile phones and little portable devices.

6. MMC Micro Card: Previously known as S-Card, this Samsung creation was introduced by the Multi Media Card Association in 2005. MMC is almost the size of a finger nail, possibly the smallest memory card in the world. It is the latest version of memory cards and is still not proven to be compatible in many handsets and electronic products. But it is definitely going to be one of the most powerful and popular memory cards of the near future.

7. Secure Digital Card: The SD Memory Card or Secure Digital created by SanDisk Corporation in collaboration with Toshiba and Panasonic is the most commonly used memory card. It is like the MMC but the only difference is that this one has a write protection switch.

8. Mini SD Card: This 1.4 mm card introduced by SanDisk along with Panasonic and Toshiba is a smaller avatar of the SD card and has the same benefits, with the exception of the write protection switch.

9. Micro SD Card: Also known as Transflash, this 1 mm card is the worlds smallest memory card, used commonly in mobile phones.

10. XD Picture Card: This 1.7 mm memory card comes branded only under Fuji Film and Olympus products, especially their digital cameras.
