App note: Bad block information introduction

App note from Macronix all about NAND flash bad blocks management. Link here (PDF) Today, NAND flash is used in many fields, such as consumer, industrial, and automotive. Compared with NOR flash, NAND flash has the advantage of availability at higher densities and lower cost per bit. However, NAND flash has the disadvantage of requiring […]

App note: Enhancing system security with Macronix(TM) flash

Technical note from Macronix about built-in and hardware security strategies on their flash memories. Link here (PDF) Attacks on a system typically alter or copy the content of the Flash image for three primary reasons, which are to: operate the system in an unauthorized manner with the purpose of committing fraud against the user or […]

App note: High density serial flash addressing

Old app note from Macronix about accessing high density serial flash. Link here (PDF) Many consumer products have converted or are converting from parallel flash to SPI serial flash. Generally, high end applications require higher memory density, but in the past, serial flash densities were limited to 128Mb due to addressing constraints.

App note: Wear leveling in NAND flash memory

Application note/Technical note from Macronix on extending the maximum endurance limit of NAND flash memories by wear leveling. Link here (PDF) NAND flash memory is widely used in today‚Äôs embedded systems for code and data storage applications. Some applications are required to perform numerous Program and Erase operations on the NAND flash memory after system […]
