Migrating from a chip enable care to a chip enable don't care NAND flash memory

All NAND flash memories offered by Numonyx have the Chip Enable don't care feature, which allows sharing the bus among several memories active at the same time, as Chip Enable transitions during the latency time do not stop read operations.

This application note aims to highlight the differences between Chip Enable don't care and Chip Enable care devices. It also explains the advantages of Chip Enable don't care NAND flash memories over Chip Enable care devices in applications.

Chip Enable don't care and standard Chip Enable care NAND flash memories differ only by the sequential row read operation which is allowed in Chip Enable care devices only. All other operations are performed in the same way using the same command set.
