NAND FLASH CONTROLLER

4.1 OVERVIEW OF NAND FLASH CONTROLLER

Owing to the recent increase in the prices of NOR flash memory and the moderately priced DRAM and NAND
flash, customers prefer to execute boot code on NAND flash and execute the main code on DRAM.
The boot code in S5PC110 can be executed on external NAND flash. It will copy NAND flash data to DRAM. To
validate the NAND flash data, S5PC110 comprises of hardware Error Correction Code (ECC). After the NAND
flash content is copied to DRAM, main program will be executed on DRAM.

4.2 KEY FEATURES OF NAND FLASH CONTROLLER

The key features of NAND flash controller include:
•
