TL;DR: In this article, a tamper-resistant module and a flash memory are used to store large-capacity data while ensuring a security level corresponding to the size of the data stored in the memory.
Patent
Transferring data between volatile and non-volatile memories based on system parameters using a controller
TL;DR: In this paper, the authors present a memory apparatus having a volatile memory for storing data from a host, a nonvolatile memory capable of storing the data stored in the volatile memory, and electrically deleting the data, and a control circuit for controlling data transfer between the volatile and non-volatile memories.
