A method and system for randomizing memory in a functional verification test of a user design is disclosed. A random number is generated during the functional verification test. The data stored in the memory of the user design is stored. Encryption keys unique for each memory address of the memory are generated. Each encryption key for each memory address is a function of the random number and the memory address. Data in each memory address of the memory is encrypted with the encryption keys unique for each memory address. After exiting a low-power or power-off state, data in each memory address is read and decrypted using the same encryption keys. Data before and after the low-power or power-off state are compared to test memory loss.
