2.1
To emulate a hard disk, a flash disk requires a software management layer. TrueFFS is M -Systems’
patented flash file system management technology that allows flash components to fully emulate hard disks,
so they can be read from and written to like any other hard disk.
TrueFFS software simplifies and enhances flash memories by:
The TrueFFS driver supports 8-bit, 16-bit, and 32-bit bus architectures. Support for the 16-bit and 32-bit
bus architectures, typically used in RISC processors, is achieved by using the LSB of the data bus as
follows:
2.2
The DiskOnChip provides full boot capability. In many cases, this allows the system engineer to remove the
boot ROM/flash device from the motherboard. The CPU can fetch and execute boot code directly from the
1KB XIP boot block of the DiskOnChip. It can then load the remainder of the boot code from the NAND
flash into the system’s RAM and continue to execute from RAM.
2.3
Integration of a flash disk in a single chip gives the DiskOnChip unique features including:
91-SR-002-32-8L Rev. 0.2
Using third-generation wear leveling to ensure that all blocks are erased an equal number of times. This
dramatically increases the life of the product. Refer to our online life expectancy calculator on the
M-Systems Web site (www.m-sys.com).
in your specific application.
Using virtual blocking of the flash device to make erasure of large blocks transparent to the operator.
Offering automatic bad block management and retirement.
Implementing a robust, power-loss recovery mechanism to guarantee protection of data.
For a 16-bit data bus, shift the address lines by one. For example: host address line A1 should be
connected to address A0 of the DiskOnChip, host address line A2 should be connected to address A1 of
the DiskOnChip, and so on.
For a 32-bit data bus, shift the address lines by two. For example: host address line A2 should be
connected to A0 of the DiskOnChip, host address line A3 should be connected to A1 of the
DiskOnChip, and so on.
Small footprint - 48-pin TSOP-I package.
Low-power consumption – internal functions are synchronized with the CPU’s read and write strobes.
This innovation eliminates the need for an external clock and provides a fully static device.
Single 3.3V power supply.
