After WRITE operations (program or erase sector) to the Flash Memory, it does not respond to any instruction during power-up except READ STATUS REGISTER, I have reset the circuit and the device remains in lock mode. I have to power down the chip to unlock the memory and get correct values (previously written) back from the EPCQL. I'm wondering if it is a normal behave of Flash memories or am I missing something..
The write bytes/erase sector command sequecing is respected and the data read back after power down being as expected. Any help or points in a direction would be much appreciated. Thank you in advance
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
Thank you for your reply.
Kindly, check the attached file given here below, you will find screenshots of my system to show you connections I have made and running results. I’m wondering if the logic inside flash memory devices requires a power down after each WRITE operation.
Your reply will be appreciated, thank you in advance.
Just an update I have replicated the scenario, we will get back on this.
In case if you have found the solution/work around can you please share the solution.
