If we look at the history, it has proved that the manufacturers and consumers both have benefited more from the open standards who give preference to single, widely supported and accepted standard. The features of microSD memory card address all the mobile device's increasing needs. The new embedded standard of secure digital provides reliable design and functionality of SD that eases to enhance the options of device storage. The SDA (SD card association) has entered the market of embedded data storage with their embedded standard of SD (secure digital) for the data storage devices.



Specification of embedded secure digital extends the interface of SD (secure digital) to the embedded data storage. The storage potential of the device is also doubled and the design platform has been eased in electronic consumer devices and mobile handsets. The next generation of consumer electronics and cell phone handsets require high capacity flash management and embedded storage solutions. Embedded secure digital is completely compatible with the SD 2.00 SDHC which is the dominating interface of industry. It allows smooth migration from the secure digital to the embedded designs of SD.

The system engineering is simplified by the embedded SD as it leverages the popular SD standards. It enables all the removable input/output peripherals and the embedded devices to use the same interface. Flash management is separated from the host by the embedded SD and also provides flexibility to the consumers and manufacturers up to high capacity scalable 32 Gigabytes on board memory along with removable memory of 32GB with any high capacity secure digital card.

The dominant removable card interfaces for the cell phones are the microSD and miniSD card. According to the analysis by the year 2010 about 90% of the memory card slots in the cell phones will constitute of the microSD and miniSD form factors. Base of the embedded secure digital standard is the dominant SD standard that focuses on the storage requirements of the cell phones like the flash management, small form factor, boot functionality and the low consumption of power. The particularization of the embedded secure digital based flash devices is regulated by the embedded standard of SD that prevents the fragmentation of market in CE and mobile industries. It also eases the storage device's integration. Specification of embedded SD describes the electrical and mechanical framework of the new form. It also focuses on the embedded device's advanced functionality.

Embedded secure digital devices provide reliable solution and also provides easy migration path. The complexity of deign is also reduced and offers more support for data storage, applications and code as well. SD card association has decided to deliver exceptional compatibility so that the market fragmentation could be reduced. SD association continues to expand the host market and ensures the development of future interface offering backward compatibility. Continuous co-operation and teamwork within the eco-system of the association fuels the engine for growth, consistency and innovation. Embedded secure digital is completely compatible with the SD 2.00 SDHC which is the dominating interface of industry. It allows smooth migration from the secure digital to the embedded designs of SD. The quantity of components of memory in the design of embedded secure digital devices is reduced because of the reliable boot code's storage.
