Disclosed are compositions and a method for amplification of nucleic acid sequences of interest. The disclosed method generally involves replication of a target sequence such that, during replication, the replicated strands are displaced from the target sequence by strand displacement replication of another replicated strand. In one form of the disclosed method, the target sample is not subjected to denaturing conditions. It was discovered that the target nucleic acids, genomic DNA, for example, need not be denatured for efficient multiple displacement amplification. The primers used can be hexamer primers. The primers can also each contain at least one modified nucleotide such that the primers are nuclease resistant. The primers can also each contain at least one modified nucleotide such that the melting temperature of the primer is altered relative to a primer of the same sequence without the modified nucleotide(s).

Disclosed are compositions and a method for of amplifying nucleic acid sequences useful for detecting the presence of molecules of interest. The method is useful for detecting specific nucleic acids in a sample with high specificity and sensitivity. The method also has an inherently low level of background signal. A preferred form of the method consists of a DNA ligation operation, an amplification operation, and a detection operation. The DNA ligation operation circularizes a specially designed nucleic acid probe molecule. This operation is dependent on hybridization of the probe to a target sequence and forms circular probe molecules in proportion to the amount of target sequence present in a sample. The amplification operation is rolling circle replication of the circularized probe. A single round of amplification using rolling circle replication results in a large amplification of the circularized probe sequences. Following rolling circle replication, the amplified probe sequences are detected and quantified using any of the conventional detection systems for nucleic acids such as detection of fluorescent labels, enzyme-linked detection systems, antibody-mediated label detection, and detection of radioactive labels. Because, the amplified product is directly proportional to the amount of target sequence present in a sample, quantitative measurements reliably represent the amount of a target sequence in a sample. Major advantages of this method are that the ligation step can be manipulated to obtain allelic discrimination, the DNA replication step is isothermal, and signals are strictly quantitative because the amplification reaction is linear and is catalyzed by a highly processive enzyme. In multiplex assays, the primer oligonucleotide used for the DNA polymerase reaction can be the same for all probes. Also described are modes of the method in which additional amplification is obtained using a cascade of strand displacement reactions.

Physically unclonable function (PUF) memory employing static random access memory (SRAM) bit cells enhanced by stress for increased PUF output reproducibility. Stress voltage applied to SRAM bit cells enhances their skew so that the SRAM bit cells output their preferred initial state in subsequent PUF read operations regardless of process variation and other external environmental variations, such as temperature. The application of stress voltage on the SRAM bit cells in a PUF memory array takes advantage of the recognition of aging effect in transistors, where turning transistors on and off over time can increase threshold voltage resulting in lower drive current. Stress voltage can be applied to the SRAM bit cells to bias their threshold voltage to simulate this aging effect to enhance mismatch between transistors in the SRAM bit cell to more fully skew the SRAM bit cells for increased PUF output reproducibility with less susceptible to noise.
