Is there any document that shows how to clear a FPGA memory?

My name is Christian Nzouakou Noche. I work from Northrop Grumman Corporation. I have some parts number here. Some of them are FPGA. I would like to obtain a procedure how to clear data from their memory for the company report. These parts are:

- EPM9560ARC240-10

- EPF10K100ABC600-1

- EPF20K100QC240-1

- EPM9560ARC240-1

- EPF10K100EFC484-1X

- EPM7064AEFC100-4

- EPM7512AEFC256-7

- EPM9560ARI240-10

- EPC2LI20N

- EPF10K30ABC356-1

- EPF10K100ARC240-1

- EPF10K100ABC356-1N

The parts that I have cited above, carry memory. Some of them are FPGAs. I would Like to acquire a sheet of each part number that show me how to clear/sanitize individual memory.
