“…Therefore, a change in the key requires modifying the mask layout. Efuse [1] and anti-fuse [2,3] are one-time programmable (OTP) memories, which can be built in a generic digital process, but the programming operation is irreversible. A battery-backed SRAM is a power-gated SRAM in data retention mode.…”

Serial RRAM Cell for Secure Bit Concealing

Non-volatile memory cells are exposed to adversary attacks since any active countermeasure is useless when the device is powered off. In this context, this work proposes the association of two serial RRAM devices as a basic cell to store sensitive data, which could solve this bothersome problem. This cell has three states: ‘1’, ‘0’, and masked. When the system is powered off or the data is not used, the cell is set to the masked state, where the cell still stores a ‘1’ or a ‘0’ but a malicious adversary is not capable of extracting the stored value using reverse engineering techniques. Before reading, the cell needs to be unmasked and it is masked afterwards until the next reading request. The operation of the cell also provides robustness against side-channel attacks. The presented experimental results confirm the validity of the proposal.

“…A 4Kx8 macro [9] was shown having almost the same program window as the 4Kx8 array [8], can be read at very low voltage and fully testable [9]. A comparison table [9] with other OTPs [5], [10]- [15] indicates the I-fuse is the best in all figures of merit. This article is an enhanced version of [9] with more data in different temperatures and process corners, and more analyses on I-fuse technology, testability and qualification.…”
