• Manufacturer Part Number: k9k1g08u0m-ycb0
• Description: 128m X 8 Bit Nand Flash Memory
• Manufacturer: Samsung Semiconductor, Inc.

Data Protection
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector
disables all functions whenever Vcc is below about 2V. WP pin provides hardware protection and is recommended to be kept at V
during power-up and power-down. A recovery time of minimum 10 s is required before internal circuit gets ready for any command
sequences as shown in Figure 25. The two step command sequence for program/erase provides additional software protection.
