3.0 Flash Management
3.1
Since the IDE Single Chip Drive provides a standard IDE interface to the host, no software integration is
required, providing the shortest time-to-market for design engineers.
The firmware of the embedded Mach1 controller contains STEC‘s advanced flash memory management
algorithms to ensure the most optimum device performance, reliability and endurance. It was designed to
maximize the benefits of flash memory, while at the same time overcoming inherent NAND flash
limitations. Implemented in firmware are the below features:

3.2
Inherent to NAND flash technology are areas (blocks) on the media that cannot be used for storage
because of their high error rate. These so-called ―bad blocks‖ are already identified by the flash vendor
during manufacturing, but can also be accumulated over time during device operation.
The Mach1 controller contains a table that lists all the bad blocks on the device (Bad Block Table), and
automatically maps out these blocks upon system initialization. During device operation it ensures that
newly accumulated bad blocks are also mapped out and added to the Bad Block Table.
Bad block management is 100% transparent to the host application, which will not be aware of the location
or existence of bad blocks on the media.
