General Description
The DiskOnChip 2000 product line is the second-generation of M-Systems’ DiskOnChip series of
products. The 2000 series provides a small, single-chip, solid-state flash disk in a standard 32-pin
DIP package. Combining a disk controller with flash memory on a single chip, DiskOnChip 2000 is
the solution where minimal weight, space, and power consumption are essential. In consequence, the
2000 series finds use today in a wide range of products, such as information appliances, set-top
boxes, thin clients, thin servers, network computers, and embedded, portable computers.
By placing DiskOnChip 2000 in a standard socket, physical space requirements are reduced. Unlike
standard IDE drives, no cables or extra space are required. DiskOnChip 2000 has no moving parts,
resulting in significantly decreased power consumption and increased reliability. It is easy to use and
reduces integration overhead. DiskOnChip 2000 is therefore a very attractive alternative to
conventional hard and floppy disk drives.
Using TrueFFS technology, DiskOnChip 2000 delivers full hard disk emulation. As such, the design
and integration stages can be considerably reduced, thereby enabling very fast time-to-market and
ease of production. Combined with its very attractive cost structure, DiskOnChip 2000 is a superior
alternative to resident flash array (RFA).
DiskOnChip 2000 products are available in capacities ranging from 16MB to 576MB. In addition,
they are 100% pinout and software compatible with the DiskOnChip Millennium DIP 8MB package.
In future versions, the capacity will be dramatically increased (up to 1GB during 2002). Since the
same pinout will be retained, the socket on the target platform will not have to be changed to
accommodate the larger capacities.
DiskOnChip technology provides broad support for all major operating systems and processors in the
market, enabling it to be readily integrated with any architecture.
DiskOnChip 2000 is shipped as a plug-and-play device that is fully tested and formatted, and
programmed with a DOS driver. Future driver, software or content upgrades, or formatting, can be
made on-board or off-board using DiskOnChip utilities and accessories provided by M-Systems.

Detailed Feature List
TrueFFS Technology
For a flash disk to emulate a hard disk, a software management layer is required. TrueFFS is
M-Systems’ patented flash file system management technology that allows flash components to fully
emulate hard disks, so they can be written to and read from like any other hard disk.
TrueFFS software simplifies and enhances flash memories by:
• Using third-generation wear leveling, which ensures that all blocks are erased an equal number of
times. This increases the life of the flash media by orders of magnitude.
• Using virtual blocking of the flash device to make erasure of large blocks transparent to the
operator.
• Automatic block mapping.
• Implementing a robust power-loss recovery mechanism to guarantee absolute protection of data.
• Providing conventional address support for various architecture configurations.
• 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, can be achieved by using the LSB of
the data bus as follows:
ƒ For 16-bit address boundary shifts, shift the address lines by one, so that the host address line
A1 connects to DiskOnChip 2000 address line A0, the host address line A2 connects to
DiskOnChip 2000 line A1, and so on.
ƒ For 32-bit address boundary shifts, shift the address lines by two, so that the host address line
A2 connects to DiskOnChip 2000 address line A0, the host address line A3 connects to
DiskOnChip 2000 line A1, and so on.
Refer to Application Note AP-DOC-030 for more details.
Low Power Consumption
The internal functions are synchronized with the CPU’s read and write strobes. This innovation
eliminates the need for an external clock and dramatically reduces power consumption.
DiskOnChip 2000 requires only a single 3.3V or 5V power supply, which helps simplify integration.
These features make DiskOnChip 2000 the best cost/performance solution for computers that require
minimal weight, space, and power consumption, providing a very attractive alternative to
conventional hard and floppy disk drives.
Temperature Range
DiskOnChip 2000 is available in both commercial (0 ºC to +70 ºC) and extended (-40 ºC to +85 ºC)
temperature ranges.
* DiskOnChip 2000 192MB and 576MB capacities are available only for commercial temperature ranges.

DiskOnChip 2000 DIP
Easy to Integrate
Fast integration is ensured by the following DiskOnChip 2000 features:
• Compatibility with standard EEPROM DIP pinout
• Support for local bus and ISA bus interface
• Small memory map window size – only 8KB
• Static operation – no clock required
• 16mA output drive (18mA at 3.3V)
Robust Error Correction
The DiskOnChip family utilizes a Reed-Solomon Error Detection Code (EDC) and Error Correction
Code (ECC), providing the following error immunity for each 512-byte block of data:
• Corrects up to two 10-bit symbols, including two random bit errors
• Corrects single bursts of up to 11 bits
• Detects single bursts of up to 31 bits, and double bursts of up to 11 bits
• Detects up to 4 random bit errors
High Reliability
DiskOnChip 2000 can be inserted into standard DIP sockets, eliminating the need for mechanical
disk drives, bulky ribbon cables and connectors. The design of DiskOnChip 2000 ensures high
reliability even when subjected to levels of shock, vibration, and temperature changes that would
destroy a conventional magnetic disk drive.
High Speed
DiskOnChip 2000 implements an integrated architecture for data transfers, which eliminates
bottlenecks typical in this area. Additionally, it doubles read performance and significantly improves
write performance, in comparison to competitive alternatives. DiskOnChip 2000 can sustain system
write speeds of over 550KB per second, read speeds of more than 1.4MB per second (measured in
ISA no wait state environment) and read/write burst transfer rates of nearly 5MB per second.
Compatibility with 8MB DiskOnChip Millennium Series
DiskOnChip 2000 is a 32-pin Dual Inline Package (DIP) that provides 100% pinout compatibility
with M-Systems' DiskOnChip Millennium DIP (8MB). DiskOnChip 2000 is fully software
compatible with M-Systems' DiskOnChip Millennium DIP (8MB), for version 1.21 and higher.

Designing with the DiskOnChip 2000 Flash Disk
4.1
Hardware
DiskOnChip 2000 should be connected as a standard memory device, using standard memory
interface signals. Typically, DiskOnChip 2000 can be mapped to any free 8KB memory space. In PC
architectures, if the memory window allocated to DiskOnChip 2000 is larger than 8KB, an automatic
anti-aliasing mechanism prevents the firmware from being loaded more than once. Figure 1
illustrates a typical interface between DiskOnChip 2000 and a system.

Software
DiskOnChip 2000, under control of TrueFFS, is accessed using standard file system calls like any
other block device. Applications can write to and read from any sector on DiskOnChip 2000, which
is compatible with all diagnostic utilities, applications and file systems.
The flash memory within DiskOnChip 2000 is accessed by TrueFFS through an 8KB window in the
CPU’s memory space. TrueFFS handles the paging of this window in the flash array, as well as
providing flash disk emulation that includes flash table management, wear leveling, mapping out bad
blocks, and background space reclamation of unused flash blocks.
The same 8KB address space will be retained in future versions of DiskOnChip 2000 that offer
greater capacities.
4.3
Designing DiskOnChip 2000 into PC Architecture
When used in PC-compatible architectures, DiskOnChip 2000 is allocated an 8KB memory window
in the BIOS expansion memory range, which is usually located between 0C8000h and 0EFFFFh.
Figure 3 illustrates the DiskOnChip 2000 memory window in relation to the PC memory map.

Figure 3: PC Memory Map
After reset, the BIOS executes the POST (Power On Self-Test), and then searches for all expansion
ROM devices. When DiskOnChip 2000 is found, the BIOS executes the Initial Program Loader
(IPL) code located in the boot-block area of DiskOnChip 2000. This code loads the TrueFFS driver
into system memory, installs DiskOnChip 2000 as a disk in the system, and then returns control back
to the BIOS code. The operating system subsequently attempts to identify disks that are available and
the DiskOnChip 2000 software (TrueFFS) responds by emulating a hard disk.
From this point onward, DiskOnChip 2000 is identified by the system as a standard disk drive. It is
assigned a drive letter and it can be used by any software application. No BIOS setup modifications,
autoexec.bat/config.sys modifications or external software are required.
• DiskOnChip 2000 can be used as the only disk in the system, in which case it will be accessed as
drive [C:].
• DiskOnChip 2000 can operate with or without a floppy drive, or with additional hard disks. When
working with a hard disk, DiskOnChip 2000 can be configured as the last drive (the default
configuration). In this case, the hard disk will be drive [C:] and DiskOnChip 2000 will be drive
[D:].
• DiskOnChip 2000 can also be configured as the first drive. In this case, the hard disk will be drive
[D:] and DiskOnChip 2000 will be drive [C:].
• DiskOnChip 2000 can be used as the boot device when configured as drive [C:]. In this
configuration, you must format DiskOnChip 2000 as a bootable device by copying the OS files
onto the disk. When running DOS, use the SYS command for this purpose.

Figure 4: DiskOnChip 2000 Simplified Block Diagram
DiskOnChip 2000 appears to the system’s hardware as a standard EEPROM, via the System
Interface block. The host cycles are passed to the Flash Control block, to be written to or read from
the flash device.
To ensure the highest level of reliability, each cycle is monitored by the EDC/ECC (Error Detection
and Correction) block. In write cycles, the EDC/ECC block generates a syndrome for every sector
that contains data, which is stored in the flash together with the sector. When the sector is read, the
syndrome is regenerated for the data and compared with the original syndrome. When a mismatch is
detected, it is repaired.
The boot block is responsible for answering the BIOS expansion search in PC architectures. After the
BIOS identifies DiskOnChip 2000 as a valid BIOS expansion device, it executes the code stored in
the boot block. The BIOS then loads the TrueFFS software from the flash memory into the host
memory, delivering full disk capabilities to the operating system. This code is identical for all
DiskOnChip 2000 capacities, since TrueFFS automatically detects the memory capacity of
DiskOnChip 2000.
6.1
Error Detection and Correction (EDC/ECC)
DiskOnChip 2000 uses the Reed-Solomon EDC/ECC algorithm to ensure high data reliability. Each
time a block of data is written to the flash, a 6-byte checksum is also written. Each time the data is
read back from the flash, a new 6-byte code is computed. TrueFFS uses these checksums for error
detection and, if necessary, error correction.

The DiskOnChip 2000 DIP device is not hermetically sealed. Therefore, it must be assembled after
the PCB goes through its final rinse. Assembling DiskOnChip 2000 prior to the rinse phase may
cause it to absorb moisture. Failure to adhere to the above assembly instruction can lead to device
failures not covered by M-Systems' warranty.
Note: DiskOnChip 2000 DIP requires a DIP socket on the target platform. Due to its plastic shell and molding material, it
cannot be soldered directly to the platform.

Note 1: CE# may be asserted any time before or after OE# is asserted. If CE# is asserted after OE#, all timing relative to
OE# asserted will be referenced instead to the time CE# was asserted.
Note 2: CE# may be negated any time before or after OE# is negated. If CE# is negated before OE#, all timing relative to
OE# negated will be referenced instead to the time CE# was negated.
