Migration from Samsung K9F1G08U0D to Cypress S34ML01G1
AN98593 details how to migrate designs from a Samsung K9F1G08U0D NAND flash memory device to a Cypress
S34ML01G1 NAND flash memory device.
1
Overview
This application note details how to migrate designs from a Samsung K9F1G08U0D NAND flash memory device
to a Cypress S34ML01G1 NAND flash memory device. The S34ML01G1 device is a 3.0 volt, x8-only, NAND flash
memory manufactured with 4x nm technology.
Note: All the information provided in this guide illustrates only the differences for each section. Please refer to the
respective data sheets for more information.
The Cypress S34ML01G NAND flash memory device is compatible with the Samsung K9F1G08U0D NAND flash
memory device with respect to block, page size, and command set.
