“…In most PUF demonstrations, the BER is well above this allowed range, thus requiring the addition of the invariably dominant area and energy cost of ECC (e.g., 2-3 orders of magnitude higher than the raw PUF and post-processing). In a few silicon demonstrations, the native BER has reached sufficiently low levels that allow the suppression of ECC in embedded DRAM PUFs [19], oxide rupture-based PUFs [45], and RRAM arrays in view of their pronounced process variations [46]. As in Fig.…”

“…As in Fig. 3c, innovation in post-processing techniques is substantially improving the stability in most PUF architectures, especially in non-volatile memory-based [46]- [50] and analog PUFs [24]- [27]. Volatile memory-based PUFs are also substantially improving [17]- [23], and allow ECC-less operation through methods such as VSS-bias generator for dark bit detection [20] and hot carrier injection-induced stability reinforcement [21].…”

“…However, the new approaches unified the TRNG with the memories used in the system, reducing the area overhead. The unified TRNG uses the different physical phenomena to generate random sequence with the undesirable effects in the Static memory (SRAM) [31], [32], Dynamic memory (DRAM) [33], [34], Resistive memory (RRAM) [35]- [38], Magnetic memory (MRAM) [39], [40]. An NVRAM with the control gate methodology can be used for TRNG applications, reading the noise while sensing their threshold voltage [10].…”
