6.7.3.4.1 Zeroization of Volatile Memories

All volatile user memories (SRAM or registers) are zeroized in all zeroization modes.

  • System Controller Memories—memories containing sensitive information are written zeros.
  • Fabric Memories—all fabric LSRAMs and µRAMs are cleared by writing zero to all the memory locations.
  • MSS RAMs (For PolarFire SoC Only)—All the MSS RAMs are zeroized
  • Fabric Registers—fabric registers content is destroyed.
