The Control and Status block contains registers responsible for transferring address, data and
control information between the DiskOnChip TrueFFS driver and the flash media. Additional
registers are used to monitor the status of the flash media (ready/busy) and the DiskOnChip
controller. For further information on the DiskOnChip registers, refer to Section 7.

Mobile DiskOnChip G3 512Mb consists of two 256Mb flash planes that consist of 1024 blocks
each, organized in 64 pages, as follows:
•
•
Parallel Multi-Plane Access
The two 256Mb flash planes operate in parallel, thereby providing a true 32-bit internal data bus
and four times the read, write and erase performance. Two pages on different planes can be

Page – Each page contains 512 bytes of user data and a 16-byte extra area that is used to store
flash management and EDC/ECC signature data, as shown in Figure 12.
Block – Each block contains 64 pages (total of 256Kb), as shown in Figure 13. A block is the
minimal unit that can be erased, and is sometimes referred to as an erase block.
Note: Since the device works with multiple planes, the operational block size is 512Kb, as
