2 Static RAM (SRAM) Memory

The device also includes an SRAM array that is used to store the input command or output result, intermediate computation values, etc. The contents of the SRAM can never be read directly, only used internally by the secure element. The entire contents of this memory are invalidated whenever the device goes into Sleep mode, tamper reset or the power is removed. SRAM Address and Data are scrambled.

TempKey

Internal memory location that stores an intermediate value used in calculations. The value cannot be read but can be used by subsequent commands.
