In this paper, a mixture of VLIW and vector architecture of ECC processor is proposed to perform either prime field GF(p) operations or binary field GF(2 m ) operations for arbitrary prime numbers and irreducible polynomials. Besides, an application specific instruction set for ECC is presented to support parallel processing with VLIW instruction structure features and vector register addressing modes. After implemented in 65-nm CMOS process, our proposed 521-bit dual field elliptic curve cryptographic processor can perform scalar multiplication in 1.3 ms over GF(p 521 ) and 0.94 ms over GF(2 521 ). Our ECC processor chip is advantageous in terms of functionality, scalability, and performance.

A high reliability system for the generation of truly random numbers, based on Resistive Random Access Memory (RRAM) has been proposed. The circuit is using the random telegraph noise (RTN) in RRAM cell as a source of noise to force more jitter into the oscillators. Because these RTN signals from the RRAM cells are much larger than that in the MOSFET and thermal noise in a resistor, then the preamplifier is not required. A prototype chip has been fabricated in SMIC 0.18um standard CMOS logic process. The test results show that the features of the proposed true random number generator (TRNG) fulfill the NIST tests for randomness.

Full-field transmission X-ray microscopy(TXM)is widely applied in basic study of science,covering microelectronics,bioscience,organic chemistry,materials science,etc [1].The key components in X-ray optics are condensers providing an illumination onto the testing samples and the high-resolution zone plate as an objective lens forming a magnified image of the sample [2,3].So the high aspect ratio(height/width)condensers and zone plates are very important.

A full-rate energy-efficient forwarded-clock (FC) receiver is demonstrated in this paper. A current sampler with continuous-time equalization is realized with 20 GHz bandwidth in sampling for data recovery. Moreover, a phase interpolator is introduced to generate sampling clock with deskew for data recovery. The testing chip was fabricated in 65 nm CMOS process in area of 0.16 mm 2 . Measurement shows that the FC receiver can achieve a data-rate up to 9.8 Gbps and power consumption is 6.5 mW.

An energy-efficient dual-band ASK transceiver for intra/inter-chip communication is proposed in this paper. The transmitter is implemented with two coupled VCOs which have two modes and generate two carrier frequencies (75 GHz/85 GHz) with low power consumption. Meanwhile, the receiver consists of a wideband LNA, an envelope detector and output buffer. The LNA has a peak gain of 27 dB at 86 GHz, a bandwidth of 28 GHz from 65 GHz to 93 GHz and a power consumption of 7 mW. Intra-chip communication channels are implemented by on-chip transmission lines. Prototype ASK transceiver is fabricated in TSMC 65 nm CMOS process with an area of 0.42 mm 2 . A spectrum and transient measurements show the bandwidth achieves up to 8 GHz with a power consumption of 13 mW.

As the semiconductor manufacturing technology continuously scales down, the working memory, such as SRAM and DRAM, suffers from the issues of dramatic leakage and power consumption. Non-volatile memories are proposed to deal with these problems. Among them, MRAM is one of the most promising candidates for DRAM replacement. However, MRAM is sensitive to external magnetic field and high temperature disturbance theoretically. In this paper, we investigate the impacts of external magnetic field and high temperature disturbance on MRAM and set up a test platform based on FPGA to analyze MRAM reliability under different external environment. Test results show that MRAM has a good thermal reliability but a notable sensitivity to external magnetic field disturbance.
