Theory of Operation
Overview
System Interface for host interface
Configuration Interface for configuring Mobile DiskOnChip Plus to operate in 8/16-bit mode, cascaded
configuration and hardware write protection.
Protection and Security-Enabling containing write/read protection and One-Time Programming (OTP),
for advanced data/code security and protection.
Programmable Boot Block with XIP capability enhanced with a Download Engine (DE) for system
initialization capability.
Reed-Solomon-based Error Detection and Error Correction Code (EDC/ECC) for on-the-fly error
handling.
Data Pipeline through which the data flows from the system to the NAND flash arrays.
Control & Status block that contains registers responsible for transferring the address, data and control
information between the TrueFFS driver and the flash
Flash Interface consists of a single 16MB NAND flash array (Figure 5). Mobile DiskOnChip Plus
achieves a 32MB capacity using two stacked 16MB devices in a dual-die package.
Bus Control for translating the host bus address, data and control signals into valid NAND flash signals.
Address Decoder to enable the relevant unit inside the DiskOnChip controller, according to the address
range received from the system interface.
