Update Yourself With The Essential Knowledge Of Secure Memory Cards

Jun 15, 2008
Computer and its memory is of course not a new topic to you. Even a small child knows the importance of memory in the computer. Now-a-days, memory is installed in the computers with the help of memory cards. But have you ever come across the secure memory card? It is the most recent development in the field of technology and a large number of people, especially those who have notebook computers, are slowly drawn towards it.

Secure memory cards are the flash cards and are developed by the leading computer companies like Toshiba and Matsushita. These secure cards are specifically developed for the devices that are portable. For instance, you can install these memory cards in your laptops and digital cameras. Its storage capacity is equal to that of other memory cards. Some companies market secure cards with 35 GB memory.

The features of these cards are well known among the consumers. Its history is very interesting. Three renowned companies in 1999 joined hands to work jointly and develop a most advanced memory card. This card, when developed, was given the name 'Secure Digital Card'.

Secure memory card works with the support of at least three modes. These modes are One-bit SD mode, Four-bit SD mode and SPI mode. The first mode deals with the data media and commands their transfer arrangement. The second mode includes extra and reassigned pins while the third mode contains a set of SD protocol equipped with micro-chip controllers.

We cannot compare secure cards with the multi media cards due to a number of differences. For instance, secure cards are particularly designed to be installed upside down in the system. Unlike MMC, secure cards are much more thicker and have higher data transfer rate. Some secure cards can serve two purposes at the same time. They are also used as the card readers apart from their data storing capacity. The speed of the secure memory cards depends on their GB capacity. Cards with standard GB transfer data has six times more speed than that of CD-ROM.

As we have discussed earlier, depending upon the format, secure memory card comes up in different kinds. All these different memory computer cards are equipped with a number of extra features. SD Plus secure digital card can be directly inserted into the USB port without any card reader. These cards show the capacity level to store more data with their digital display.

If this card is installed in the digital camera, the captured images can directly transfer to the windows of the personal computer without any cable connections and ports. Secure digital memory card is best in every way. If you possess the latest model of laptop, then why not go for the latest technology in your memory card as well?
